| 13 | +-----------------------------------------------------------------------+ |
| 14 | |
| 15 | _KPOSIX_VERSION and P1003_1B OPTIONS REMOVED |
| 16 | -------------------------------------------- |
| 17 | |
| 18 | The _KPOSIX_VERSION and P1003_1B kernel options have been changed to |
| 19 | no-ops. They can be removed from custom kernel configurations. |
| 20 | |
| 21 | SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT |
| 22 | -------------------------------------------- |
| 23 | |
| 24 | Many more sound devices may be detected. |
| 25 | |
| 26 | If the default device choosen isn't to your liking, setting the sysctl |
| 27 | hw.snd.default_unit to a different number will change it. |
| 28 | |
| 29 | SCTP SUPPORT DROPPED |
| 30 | -------------------- |
| 31 | |
| 32 | Support for the SCTP protocol has been removed. |
| 33 | |
| 34 | OLD USB DRIVERS REMOVED |
| 35 | ----------------------- |
| 36 | |
| 37 | The old USB stack, along with the kernel config option "device oldusb" |
| 38 | and the make.conf variable "WANT_OLDUSB" have been removed. This means |
| 39 | that for custom kernel configuration files which were derived from a |
| 40 | GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default, |
| 41 | various (old USB stack specific) devices will now complain about being |
| 42 | unknown: |
| 43 | |
| 44 | * oldusb (obviously) |
| 45 | * natausb (not yet ported to usb4bsd) |
| 46 | * rue (not yet ported to usb4bsd) |
| 47 | * ugen (no longer needed in usb4bsd) |
| 48 | * urio (not yet ported to usb4bsd) |
| 49 | * uscanner (no longer needed in usb4bsd) |
| 50 | |
| 51 | They should be removed or commented out in such custom kernel configs. |
| 52 | |
| 53 | GCC 5.0 |
| 54 | ------- |
| 55 | |
| 56 | The GCC 4.4 compiler has been retired. It has been replaced by a |
| 57 | [prerelease] version of GCC 5.0. The following make.conf variables no |
| 58 | longer work: NO_GCC44, NO_OBJC, and NO_CXX. The latter was never |
| 59 | documented and the latest versions of GCC are partially written in C++ |
| 60 | so a C++ compiler is no longer optional. In practical terms it has not |
| 61 | been optional for many years as other base components are also written in |
| 62 | C++. The resource savings by avoiding building Objective-C compiler is |
| 63 | so small, the complexity added by NO_OBJC internally was deemed a bad |
| 64 | tradeoff so that is the reason for its removal. Also note that no "info" |
| 65 | pages are installed with GCC 5.0. This is intentional; they are available |
| 66 | via the internet if desired over the installed man pages. |
| 67 | |
| 68 | Currently, GCC 4.7 is still designated as the primary compiler. After |
| 69 | GCC 5.0 is released, this may change and these update notes will be |
| 70 | revised accordingly. DPorts will use GCC 5.0 on this release regardless. |
| 71 | If GCC 5.0 is unwanted, the make.conf variable NO_GCC50 will block its |
| 72 | building and installation. |
| 73 | |
| 74 | To use GCC 5.0 to build world and kernel, set WORLD_CCVER=gcc50 in |
| 75 | make.conf before building those targets. |
| 76 | |
| 77 | +-----------------------------------------------------------------------+ |
| 78 | + UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS + |
| 79 | +-----------------------------------------------------------------------+ |
| 80 | |
| 81 | SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN |
| 82 | ------------------------------------------- |
| 83 | |
| 84 | DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is |
| 85 | the default now (even on single-core systems), both for, like, 21 months. |
| 86 | We kept the options around as no-ops as a convenience, to allow people |
| 87 | using the same config for the then current release and the then current |
| 88 | master. That period is now over, so any configs still having those |
| 89 | options have to be adjusted. |
| 90 | |
| 91 | SYSVIPC SYSCALLS MADE NON-OPTIONAL |
| 92 | ---------------------------------- |
| 93 | |
| 94 | The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is |
| 95 | now compiled in by default. The options are no-ops for now. |
| 96 | |
| 97 | DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS |
| 98 | -------------------------------------------------------------------- |
| 99 | |
| 100 | The default driver for those controllers is now mrsas(4) due to reports |
| 101 | of file system corruption using the mfi(4) driver. The whole issue (and |
| 102 | how to deal with potential problems when switching) was explained here: |
| 103 | |
| 104 | http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html |
| 105 | |
| 106 | A tunable is provided for letting those controllers still attach via |
| 107 | the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page). |
| 108 | |
| 109 | OLDER NETWORK DRIVERS MOVED TO I386 ONLY |
| 110 | ---------------------------------------- |
| 111 | |
| 112 | The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar |
| 113 | and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be |
| 114 | removed in kernel configs derived from X86_64_GENERIC. |
| 115 | |
| 116 | +-----------------------------------------------------------------------+ |
| 117 | + UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS + |
| 118 | +-----------------------------------------------------------------------+ |
| 119 | |
| 120 | UPDATE FROM MOST RECENT 3.6 |
| 121 | --------------------------- |
| 122 | |
| 123 | Versions of 3.6 built before June 25th have a bug where installworld might |
| 124 | crash during installation of the new initrd. Upgrade to the latest version |
| 125 | of 3.6 before updating to 3.8 or later. |
| 126 | |
| 127 | ATM, IPX, NCP AND NWFS SUPPORT DROPPED |
| 128 | -------------------------------------- |
| 129 | |
| 130 | Support for the IPX and NCP network protocols and for mouting NetWare |
| 131 | file systems has been dropped. Dito for ATM protocol support. |
| 132 | |
| 133 | INITRD IMAGES NOW INSTALLED BY DEFAULT |
| 134 | -------------------------------------- |
| 135 | |
| 136 | An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz |
| 137 | |
| 138 | Older images installed under the file name of initrd.img will be removed |
| 139 | automatically by the make upgrade process. |
| 140 | |
| 141 | USB4BSD IS NOW THE DEFAULT USB STACK |
| 142 | ------------------------------------ |
| 143 | |
| 144 | To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and |
| 145 | replace "device usb" with "device oldusb" in the kernel configuration. |
| 146 | |
| 147 | MORE ISA SUPPORT DROPPED |
| 148 | ------------------------ |
| 149 | |
| 150 | ISA support has been dropped from the following drivers: adv(4), an(4), |
| 151 | ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4), |
| 152 | si(4), sn(4), and stg(4). |

| 154 | +-----------------------------------------------------------------------+ |
| 155 | + UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS + |
| 156 | +-----------------------------------------------------------------------+ |
| 157 | |
| 158 | ABI CHANGE |
| 159 | ---------- |
| 160 | |
| 161 | Installed third-party software (dports) will have to be rebuilt after upgrade, |
| 162 | or reinstalled from binary packages. |
| 163 | |
| 164 | UPDATING FROM 3.4 TO 3.6 |
| 165 | ------------------------ |
| 166 | |
| 167 | This only applies for this specific upgrade due to locale changes; it is |
| 168 | not needed for upgrades after 3.6. Please update in this order: |
| 169 | |
| 170 | make buildworld |
| 171 | make buildkernel |
| 172 | make installworld |
| 173 | make installkernel |
| 174 | *reboot* |
| 175 | make upgrade |
| 176 | |
| 177 | See this mailing list post for details: |
| 178 | http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html |
| 179 | |
| 180 | CYRIX OPTIONS REMOVED |
| 181 | --------------------- |
| 182 | |
| 183 | The following Cyrix related options have been removed: CPU_BTB_EN, |
| 184 | CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER, |
| 185 | CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT, |
| 186 | CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS |
| 187 | |
| 188 | ISA SUPPORT REMOVED FROM RP(4) |
| 189 | ------------------------------ |
| 190 | |
| 191 | ISA support has been removed from the rp(4) driver. It is now PCI only. |
| 192 | |
| 193 | +-----------------------------------------------------------------------+ |
| 194 | + UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS + |
| 195 | +-----------------------------------------------------------------------+ |
| 196 | |
| 197 | COMPAT_SUNOS OPTION REMOVED |
| 198 | --------------------------- |
| 199 | |
| 200 | The COMPAT_SUNOS option has been removed. It was meant to provide binary |
| 201 | compatibility with SunOS 4.x for the sparc32 port of 4.4BSD. |
| 202 | |
| 203 | ISA SOUND CARD SUPPORT REMOVED |
| 204 | ------------------------------ |
| 205 | |
| 206 | The following modules have been removed (all for ISA sound cards): |
| 207 | snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko |
| 208 | |
| 209 | GCC 4.7 |
| 210 | ------- |
| 211 | |
| 212 | DragonFly has switched base compilers. GCC 4.7 is now the default |
| 213 | compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make |
| 214 | variable ceases to work now. |
| 215 | |
| 216 | Users who wish to build only GCC 4.7 have to use NO_GCC44 in the |
| 217 | /etc/make.conf to prohibit GCC 4.4 from building. However, using it is |
| 218 | highly discouraged. There are a few packages in pkgsrc that do not build |
| 219 | with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At |
| 220 | this time, it is recommended to keep both compilers on the base system. |
| 221 | |
| 222 | SMP OPTION REMOVED |
| 223 | ------------------ |
| 224 | |
| 225 | The SMP kernel option has been made a no-op. All kernels now feature SMP |
| 226 | support. If you have 'options SMP' in your kernel config, you can as well |
| 227 | remove it. |
| 228 | |
| 229 | DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED |
| 230 | --------------------------------------------------------------------------- |
| 231 | |
| 232 | The DEVICE_POLLING kernel option has been made a no-op and it has been |
| 233 | replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your |
| 234 | kernel config, you need to change it to IFPOLL_ENABLE. |
| 235 | |
| 236 | Also, the KTR_POLLING kernel option has been removed, so it must be |
| 237 | removed from kernel configs that have it. |
| 238 | |
| 239 | BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED |
| 240 | --------------------------------------------------- |
| 241 | |
| 242 | The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA |
| 243 | cards will no longer be detected. |
| 244 | |
| 245 | The same has been done for Stallion multiport serial controllers. stli(4) |
| 246 | has been completely removed (along with the stlload(8) and stlstty(8) |
| 247 | utilities) and stl(4) was changed to support only PCI cards. Similarly, |
| 248 | ISA support was removed from cy(4) too. All these drivers are i386 only. |
| 249 | |
| 250 | COMPAT_OLDISA OPTION GONE |
| 251 | ------------------------- |
| 252 | |
| 253 | The i386 specific COMPAT_OLDISA kernel option has been removed, since |
| 254 | nothing needs it anymore. |
| 255 | |
| 256 | +-----------------------------------------------------------------------+ |
| 257 | + UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS + |
| 258 | +-----------------------------------------------------------------------+ |
| 259 | |
| 260 | APIC_IO OPTION REMOVED |
| 261 | ---------------------- |
| 262 | |
| 263 | The APIC_IO kernel option is no longer accepted after having been without |
| 264 | effect for a while. The hw.ioapic_enable tunable now serves its purpose. |
| 265 | If you have 'options APIC_IO' in your kernel config, you'll have to |
| 266 | remove it. |
| 267 | |
| 268 | WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED |
| 269 | ----------------------------------------- |
| 270 | |
| 271 | The wdog framework is now compiled into our kernels by default, so the |
| 272 | options are no longer needed. |
| 273 | |
| 274 | DOSCMD(1) REMOVED |
| 275 | ----------------- |
| 276 | |
| 277 | doscmd(1) has been removed. It was i386 only. The doscmd(1) specific |
| 278 | NO_X make.conf option was removed too. |
| 279 | |
| 280 | GCC 4.7 |
| 281 | ------- |
| 282 | |
| 283 | GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non- |
| 284 | default compiler in base (default is still GCC 4.4). |
| 285 | |
| 286 | Users who wish to build only GCC 4.4 have to replace NO_GCC41 with |
| 287 | NO_GCC47 in /etc/make.conf. |
| 288 | |
| 289 | USB4BSD |
| 290 | ------- |
| 291 | |
| 292 | A new USB stack (from FreeBSD) has been brought in. The following |
| 293 | modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass, |
| 294 | usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk, |
| 295 | and uaudio. |
| 296 | |
| 297 | It is not yet the default. To activate it, WANT_USB4BSD=yes has to |
| 298 | be put in make.conf and device "usb4bsd" (quotes needed) has to |
| 299 | replace device usb in the kernel config. After that, a full |
| 300 | build/install/upgrade cycle is needed. |
| 301 | |
| 302 | Note that this is experimental and incomplete, but we are interested |
| 303 | in hearing about issues with it, of course. |
| 304 | |
| 305 | ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER |
| 306 | --------------------------------------------- |
| 307 | |
| 308 | ISA adapter support was dropped from the aic(4) driver. |
| 309 | |
| 310 | +-----------------------------------------------------------------------+ |
| 311 | + UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS + |
| 312 | +-----------------------------------------------------------------------+ |
| 313 | |
| 314 | SEVERAL ISA DRIVERS REMOVED |
| 315 | --------------------------- |
| 316 | |
| 317 | The following ISA only drivers have been removed along with a couple of |
| 318 | associated userland tools: |
| 319 | |
| 320 | aha(4) |
| 321 | asc(4) & sasc(1) |
| 322 | ctx |
| 323 | dgb(4) |
| 324 | el(4) |
| 325 | gpib |
| 326 | gsc(4) & sgsc(1) |
| 327 | ie(4) |
| 328 | labpc(4) |
| 329 | le(4) |
| 330 | mse(4) |
| 331 | rc(4) |
| 332 | rdp(4) |
| 333 | spigot |
| 334 | tw(4) & xten(1) & xtend(8) |
| 335 | wl(4) & wlconfig(8) |
| 336 | wt(4) |
| 337 | |
| 338 | Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC |
| 339 | config and one (aha(4)) is in our X86_64_GENERIC kernel configuration |
| 340 | file. |
| 341 | |
| 342 | If buildkernel complains about any of these drivers, just remove them |
| 343 | from your kernel configuration. |
| 344 | |
| 345 | BINUTILS 2.20 |
| 346 | ------------- |
| 347 | Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted |
| 348 | values of BINUTILSVERS are now binutils221 and binutils222 (default). |
| 349 | |
| 350 | BUILDWORLD/-KERNEL PARALLELIZATION WORK |
| 351 | --------------------------------------- |
| 352 | Due to changes in the way we build with more than one make job, you |
| 353 | will have to update install(1) and mkdir(1) prior to buildworld if you |
| 354 | want to build with 'make -j': |
| 355 | |
| 356 | cd /usr/src/usr.bin/xinstall; make; make install; make clean |
| 357 | cd /usr/src/bin/mkdir; make; make install; make clean |
| 358 | |
| 359 | DMA(8) UPGRADE |
| 360 | -------------- |
| 361 | dma(8) has been upgraded to v0.7 which no longer supports the |
| 362 | /etc/dma/virtusertable. Some of its functionality has been replaced |
| 363 | with the MASQUERADE keyword and the EMAIL environment variable (see |
| 364 | the dma(8) manual page). |
| 365 | |
| 366 | +-----------------------------------------------------------------------+ |
| 367 | + UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS + |
| 368 | +-----------------------------------------------------------------------+ |
| 369 | |
| 370 | GCC 4.4 & BINUTILS 2.21 |
| 371 | ----------------------- |
| 372 | |
| 373 | GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has |
| 374 | been made DragonFly's default Binutils. |
| 375 | |
| 376 | That means that any settings that set CCVER to 'gcc44' are not needed |
| 377 | anymore. Instead, CCVER can be set to 'gcc41' to go back to using |
| 378 | GCC 4.1. |
| 379 | |
| 380 | It also means that 'binutils221' as a value for BINUTILSVER has no |
| 381 | effect anymore. 2.17 has been removed and 'binutils220' is available |
| 382 | as an option. |
| 383 | |
| 384 | The NO_GCC44 option has been removed and will not affect the build |
| 385 | anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from |
| 386 | building in a similar fashion. |
| 387 | |
| 388 | Note that you must do a full buildworld/buildkernel for upgrading. |
| 389 | |
| 390 | pkg_radd settings |
| 391 | ----------------- |
| 392 | |
| 393 | The config file for pkg_radd has moved from /etc/settings.conf to |
| 394 | /etc/pkg_radd.conf. Save the contents of settings.conf before upgrading |
| 395 | if this is needed. This warning only applies if /etc/settings.conf |
| 396 | exists. pkg_radd will continue to work with defaults. |
| 397 | |

| 400 | + UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD + |
| 401 | +-----------------------------------------------------------------------+ |
| 402 | |
| 403 | OpenSSL |
| 404 | -------- |
| 405 | |
| 406 | OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto. |
| 407 | This shouldn't break any 3rd-party software, but you'll need to recompile your |
| 408 | 3rd-party software if you want it to link against the new version of OpenSSL. |
| 409 | |
| 410 | Loader |
| 411 | ------- |
| 412 | |
| 413 | A new loader (dloader) has been added which better handles booting from |
| 414 | multiple kernel/module versions. |
| 415 | |
| 416 | To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below) |
| 417 | |
| 418 | cd /usr/src |
| 419 | make buildworld |
| 420 | make installworld |
| 421 | make upgrade |
| 422 | make buildkernel KERNCONF=<KERNELNAME> |
| 423 | make installkernel KERNCONF=<KERNELNAME> |
| 424 | |
| 425 | Note that you must installworld and run the 'upgrade' target before |
| 426 | installing the new kernel. |
| 427 | |
| 428 | BIND |
| 429 | ----- |
| 430 | |
| 431 | BIND has been removed from the base system. The ldns and drill tools have |
| 432 | been added for basic functionality. Use 'drill' where you would normally |
| 433 | use nslookup or dig, or install BIND from pkgsrc. It's available as |
| 434 | net/bind95, net/bind96, or net/bind97 as of this writing. |
| 435 | |
| 436 | This only affects older systems upgrading to 2.8. New 2.8+ installs |
| 437 | include BIND as a pkgsrc package. |
| 438 | |
| 439 | +-----------------------------------------------------------------------+ |
| 440 | + UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + |
| 441 | + GENERAL + |
| 442 | +-----------------------------------------------------------------------+ |
| 443 | |
| 444 | Instructions on how to obtain and maintain DragonFly source code using git |
| 445 | are in the development(7) manual page. |
| 446 | |
| 447 | To upgrade a DragonFly system from sources you run the following sequence: |
| 448 | |
| 449 | cd /usr/src |
| 450 | make buildworld |
| 451 | make buildkernel KERNCONF=<KERNELNAME> |
| 452 | make installkernel KERNCONF=<KERNELNAME> |
| 453 | make installworld |
| 454 | |
| 455 | You will also want to run the 'upgrade' target to upgrade your /etc and the |
| 456 | rest of your system. The upgrade target is aware of stale files created by |
| 457 | older DragonFly installations and should delete them automatically. |
| 458 | |
| 459 | make upgrade |
| 460 | |
| 461 | See the build(7) manual page for further information. |
| 462 | |
| 463 | Once you've done a full build of the world and kernel you can do incremental |
| 464 | upgrades of either by using the 'quickworld' and 'quickkernel' targets |
| 465 | instead of 'buildworld' and 'buildkernel'. If you have any problems with |
| 466 | the quick targets, try updating your repo first, and then a full buildworld |
| 467 | and buildkernel as shown above, before asking for help. |
| 468 | |

| 472 | |
| 473 | In 2.1 kernel and modules has moved to boot directory. For most cases |
| 474 | this is handled automatically by 'make upgrade'. A few cases needs manual |
| 475 | intervention: |
| 476 | |
| 477 | * When installing a kernel without first doing a make buildworld, |
| 478 | installworld and upgrade to the same DESTDIR as kernel: |
| 479 | make DESTDIR/boot directory and move kernel and modules into this boot |
| 480 | directory; also move kernel.old and modules.old. |
| 481 | Typical example is vkernel(7), use (no modules used): |
| 482 | |
| 483 | cd /var/vkernel |
| 484 | mkdir boot |
| 485 | chflags noschg kernel |
| 486 | mv kernel kernel.old boot |
| 487 | chflags schg boot/kernel |
| 488 | |
| 489 | * When using a boot-only partition, /boot/loader.rc needs to be edited: |
| 490 | delete occurrences of '/boot/'. |
| 491 | These occurences can normally be deleted in any case, see loader(8). |
| 492 | |
| 493 | +-----------------------------------------------------------------------+ |
| 494 | + UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 + |
| 495 | +-----------------------------------------------------------------------+ |
| 496 | |
| 497 | In 1.9 major changes to the disk management infrastructure have taken |
| 498 | place. make upgrade may not catch all of your disk devices in /dev, |
| 499 | so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah> |
| 500 | are all of your disk devices. HOWEVER, from late 2.3 on we run devfs |
| 501 | and MAKEDEV no longer exists. |
| 502 | |
| 503 | The biggest changes in 1.9 are: |
| 504 | |
| 505 | (1) That whole-slice devices such as da0s1 no longer share the same device |
| 506 | id as partition c devices such as da0s1c. |
| 507 | |
| 508 | (2) The whole-disk device (e.g. da0) is full raw access to the disk, |
| 509 | with no snooping or reserved sectors. Consequently you cannot run |
| 510 | disklabel on this device. Instead you must run disklabel on a |
| 511 | whole-slice device. |
| 512 | |
| 513 | (3) The 'compatibility' partitions now use slice 0 in the device name, |
| 514 | so instead of da0a you must specify da0s0a. Also, as per (1) above, |
| 515 | accessing the disklabel for the compatibility partitions must be |
| 516 | done via slice 0 (da0s0). |
| 517 | |
| 518 | (4) Many device drivers that used to fake up labels, such as CD, ACD, VN, |
| 519 | and CCD now run through the disk management layer and are assigned |
| 520 | real disk management devices. VN and CCD in particular do not usually |
| 521 | use a MBR and disklabels must be accessed through the compatibility |
| 522 | slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you |
| 523 | don't name it 'ccd0s0' in the config file. |
| 524 | |
| 525 | Generally speaking, you have to get used to running fdisk and disklabel on |
| 526 | the correctly specified device names. A lot of the wiggle, such as running |
| 527 | disklabel on a partition, has been removed. |

| 533 | > Kerberos IV |
| 534 | ------------- |
| 535 | |
| 536 | Kerberos IV (eBones) was removed from the tree, please consider moving to |
| 537 | Kerberos 5 (Heimdal). |
| 538 | |
| 539 | > Package Management System |
| 540 | --------------------------- |
| 541 | |
| 542 | Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package |
| 543 | management system. The necessary tools to build and maintain packages |
| 544 | are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these |
| 545 | directories are in your PATH variable. |
| 546 | |
| 547 | In order to obtain a reasonably current snapshot of the pkgsrc tree, use |
| 548 | the tarball from NetBSD: |
| 549 | |
| 550 | fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz |
| 551 | cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc |
| 552 | |
| 553 | This tree can then be kept up to date with cvs update: |
| 554 | |
| 555 | cd /usr/pkgsrc; cvs up |
| 556 | |
| 557 | NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to |
| 558 | build and install the pkgsrc bootstrap manually: |
| 559 | |
| 560 | cd /usr/pkgsrc/bootstrap |
| 561 | ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg |

| 567 | +-----------------------------------------------------------------------+ |
| 568 | |
| 569 | The compatibility shims for the build environment have been removed, you |
| 570 | have to update to DragonFly 1.2 release branch first. |
| 571 | |
| 572 | The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/. |
| 573 | The existing configuration can be converted using /etc/pam.d/convert.sh. |
| 574 | Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition |
| 575 | the pam_skey.so module was retired, you have to remove it manually from |
| 576 | your configuration, when you convert it. |
| 577 | |
| 578 | > Required user and group IDs when upgrading from either FreeBSD or DragonFly |
| 579 | --------------------- |
| 580 | |
| 581 | The following users may be missing from your password file. Use vipw and |
| 582 | add any that are missing: |

| 595 | > Upgrading to DragonFly from FreeBSD |
| 596 | --------------------- |
| 597 | |
| 598 | You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or |
| 599 | FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing |
| 600 | FreeBSD. Note that the DragonFly buildworld target does not try to reuse |
| 601 | make depend information, it starts from scratch, so no pre-cleaning of the |
| 602 | object hierarchy is necessary. |
| 603 | |
| 604 | # get the CVS repository (it is placed in /home/dcvs, 500MB). |
| 605 | # Please use the -h option and a mirror site to pull the |
| 606 | # initial repository, but feel free to use the main repository |
| 607 | # machine to pull updates. |
| 608 | cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile |
| 609 | # install the source from the CVS hierarchy (remove preexisting |
| 610 | # FreeBSD src first) (500MB) |
| 611 | cd /usr |
| 612 | rm -rf src |
| 613 | cvs -R -d /home/dcvs checkout -P src |
| 614 | |
| 615 | # build it (500MB used in /usr/obj) |
| 616 | # |
| 617 | cd /usr/src |
| 618 | make buildworld |
| 619 | make buildkernel KERNCONF=<KERNELNAME> |
| 620 | |
| 621 | Once you have built DragonFly you have to install it over FreeBSD. Since |
| 622 | DragonFly does not track changes made by FreeBSD to its include file |
| 623 | hierarchy and include file pollution can cause all sorts of unexpected |
| 624 | compilation issues to come up, it is best to wipe your include hierarchy |
| 625 | prior to installing DragonFly. Note that you should not wipe any installed |
| 626 | FreeBSD header files or binaries until after you have successfully completed |
| 627 | the build steps above. |
| 628 | |
| 629 | rm -rf /usr/include |
| 630 | mkdir /usr/include |
| 631 | make installkernel KERNCONF=<KERNELNAME> |
| 632 | make installworld |
| 633 | |
| 634 | Then you need to upgrade your system. DragonFly's 'make upgrade' target |
| 635 | will unconditionally upgrade the /etc files that sysops do not usually |
| 636 | mess around with, such as the files in /etc/rc.d. It will also remove any |
| 637 | obsolete files such as utilities and manpages that have been removed from |
| 638 | the system since the version you're coming from. If you are unsure we |
| 639 | recommend that you make a backup of at least your /etc before applying |
| 640 | this step. Note that DragonFly's RC system is basically RCNG from |
| 641 | FreeBSD-5, but there are some differences in the contents of the RC files. |
| 642 | |
| 643 | make upgrade |
| 644 | |
| 645 | NOTE! Never do a 'make upgrade' before 'make installworld' has been run. |
| 646 | Doing so might leave your system in an unusable state. |
| 647 | |
| 648 | Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, |
| 649 | /usr/bin, and /usr/lib, and remove any stale files that you find. Please |
| 650 | report these files to the DragonFly developers so that they can be added to |
| 651 | the 'upgrade' target. |
