To upgrade a DragonFly system from sources you run the following sequence: cd /usr/src make buildworld make buildkernel KERNCONF= make installkernel KERNCONF= make installworld You will also want to run the 'upgrade' target to upgrade your /etc and the rest of your system. The upgrade target is aware of stale files created by older DragonFly installations and should delete them automatically. make upgrade See the build(7) manual page for further information. Once you've done a full build of the world and kernel you can do incremental upgrades of either by using the 'quickworld' and 'quickkernel' targets instead of 'buildworld' and 'buildkernel'. If you have any problems with the quick targets, try updating your repo first, and then a full buildworld and buildkernel as shown above, before asking for help. +-----------------------------------------------------------------------+ + UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 + +-----------------------------------------------------------------------+ In 2.1 kernel and modules has moved to boot directory. For most cases this is handled automatically by 'make upgrade'. A few cases needs manual intervention: * When installing a kernel without first doing a make buildworld, installworld and upgrade to the same DESTDIR as kernel: make DESTDIR/boot directory and move kernel and modules into this boot directory; also move kernel.old and modules.old. Typical example is vkernel(7), use (no modules used): cd /var/vkernel mkdir boot chflags noschg kernel mv kernel kernel.old boot chflags schg boot/kernel * When using a boot-only partition, /boot/loader.rc needs to be edited: delete occurrences of '/boot/'. These occurences can normally be deleted in any case, see loader(8). +-----------------------------------------------------------------------+ + UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 + +-----------------------------------------------------------------------+ In 1.9 major changes to the disk management infrastructure have taken place. make upgrade may not catch all of your disk devices in /dev, so after upgrading be sure to cd /dev; ./MAKEDEV where are all of your disk devices. The biggest changes in 1.9 are: (1) That whole-slice devices such as da0s1 no longer share the same device id as partition c devices such as da0s1c. (2) The whole-disk device (e.g. da0) is full raw access to the disk, with no snooping or reserved sectors. Consequently you cannot run disklabel on this device. Instead you must run disklabel on a whole-slice device. (3) The 'compatibility' partitions now use slice 0 in the device name, so instead of da0a you must specify da0s0a. Also, as per (1) above, accessing the disklabel for the compatibility partitions must be done via slice 0 (da0s0). (4) Many device drivers that used to fake up labels, such as CD, ACD, VN, and CCD now run through the disk management layer and are assigned real disk management devices. VN and CCD in particular do not usually use a MBR and disklabels must be accessed through the compatibility slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you don't name it 'ccd0s0' in the config file. Generally speaking, you have to get used to running fdisk and disklabel on the correctly specified device names. A lot of the wiggle, such as running disklabel on a partition, has been removed. +-----------------------------------------------------------------------+ + UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD + +-----------------------------------------------------------------------+ > Kerberos IV ------------- Kerberos IV (eBones) was removed from the tree, please consider moving to Kerberos 5 (Heimdal). > Package Management System --------------------------- Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package management system. The necessary tools to build and maintain packages are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these directories are in your PATH variable. In order to obtain a reasonably current snapshot of the pkgsrc tree, use the tarball from NetBSD: fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc This tree can then be kept up to date with cvs update: cd /usr/pkgsrc; cvs up NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to build and install the pkgsrc bootstrap manually: cd /usr/pkgsrc/bootstrap ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg +-----------------------------------------------------------------------+ + UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + + UPDATING FROM PRE-1.2 SYSTEMS OR FreeBSD 4.x TO + + DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) + +-----------------------------------------------------------------------+ The compatibility shims for the build environment have been removed, you have to update to DragonFly 1.2 release branch first. The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/. The existing configuration can be converted using /etc/pam.d/convert.sh. Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition the pam_skey.so module was retired, you have to remove it manually from your configuration, when you convert it. > Required user and group IDs when upgrading from either FreeBSD or DragonFly --------------------- The following users may be missing from your password file. Use vipw and add any that are missing: smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin _pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin The following groups may be missing from your group file. Use vi /etc/group and add any that are missing: smmsp:*:25: authpf:*:63: _pflogd:*:64: > Upgrading to DragonFly from FreeBSD --------------------- You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing FreeBSD. Note that the DragonFly buildworld target does not try to reuse make depend information, it starts from scratch, so no pre-cleaning of the object hierarchy is necessary. # get the CVS repository (it is placed in /home/dcvs, 500MB). # Please use the -h option and a mirror site to pull the # initial repository, but feel free to use the main repository # machine to pull updates. cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile # install the source from the CVS hierarchy (remove preexisting # FreeBSD src first) (500MB) cd /usr rm -rf src cvs -R -d /home/dcvs checkout -P src # build it (500MB used in /usr/obj) # cd /usr/src make buildworld make buildkernel KERNCONF= Once you have built DragonFly you have to install it over FreeBSD. Since DragonFly does not track changes made by FreeBSD to its include file hierarchy and include file pollution can cause all sorts of unexpected compilation issues to come up, it is best to wipe your include hierarchy prior to installing DragonFly. Note that you should not wipe any installed FreeBSD header files or binaries until after you have successfully completed the build steps above. rm -rf /usr/include mkdir /usr/include make installkernel KERNCONF= make installworld Then you need to upgrade your system. DragonFly's 'make upgrade' target will unconditionally upgrade the /etc files that sysops do not usually mess around with, such as the files in /etc/rc.d. It will also remove any obsolete files such as utilities and manpages that have been removed from the system since the version you're coming from. If you are unsure we recommend that you make a backup of at least your /etc before applying this step. Note that DragonFly's RC system is basically RCNG from FreeBSD-5, but there are some differences in the contents of the RC files. make upgrade NOTE! Never do a 'make upgrade' before 'make installworld' has been run. Doing so might leave your system in an unusable state. Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, /usr/bin, and /usr/lib, and remove any stale files that you find. Please report these files to the DragonFly developers so that they can be added to the 'upgrade' target.
