1 DRAGONFLY CDROM README FILE
3 This CDROM boots DragonFly BSD. Basically what you get is a full base
4 system on CD with certain critical directories, such as /tmp, remounted
5 read-write using MFS. Your existing hard drive is not effected by
8 NOTE!!! DRAGONFLY IS UNDERGOING DEVELOPMENT AND CONSIDERED EXPERIMENTAL!
9 BSD RELATED EXPERIENCE IS REQUIRED TO USE THIS CDROM.
11 If you just want to play with DragonFly and not mess with your hard disk,
12 this CDROM boots into a fully operational console-based system, though
13 without swap it should be noted that you are limited by available memory.
15 AUTOMATIC INSTALLATION
17 We are currently developing automatic installation tools. There are none
22 Manual installation of DragonFly onto an HD involve the following sequence
23 of commands. You must be familiar with BSD style UNIX systems to do
24 installations manually. The primary IDE hard drive is typically 'ad0'
25 and DragonFly is typically installed onto the first slice.
28 # This COMPLETE WIPES and repartitions your hard drive
31 # This installs boot blocks onto the HD and verifies their
36 # This creates an initial label on the first slice of the HD. If
37 # you have problems booting you could try wiping the first 32 blocks
38 # of the slice with dd and then reinstalling the label
40 # dd if=/dev/zero of=/dev/ad0s1 bs=32k count=16
41 disklabel -B -r -w ad0s1 auto
43 # Edit the label. Create various standard partitions. The typical
46 # ad0s1a 256m This will be your /
47 # ad0s1b 1024m This will be your swap
48 # ad0s1c (leave alone)
49 # ad0s1d 256m This will be your /var
50 # ad0s1e 256m This will be your /tmp
51 # ad0s1f 8192m This will be your /usr (min 4096m)
52 # ad0s1g * All remaining space to yoru /home
56 # Newfs (format) the various filesystems. Softupdates is not
57 # normally enabled on the root filesystem.
65 # Mount the filesystems
67 mount /dev/ad0s1a /mnt
72 mount /dev/ad0s1d /mnt/var
73 mount /dev/ad0s1e /mnt/tmp
74 mount /dev/ad0s1f /mnt/usr
75 mount /dev/ad0s1g /mnt/home
77 # Copy the CDRom onto the target. cpdup won't cross mount boundaries
78 # on the source (e.g. the MFS remounts) so it takes a few commands.
85 # Cleanup. Also, with /tmp a partition it is usually reasonable
86 # to make /var/tmp a softlink to /tmp
90 ln -s /tmp /mnt/var/tmp
92 # Edit /mnt/etc/fstab to reflect the new mounts. An example fstab
93 # file based on the above parameters exists as /mnt/etc/fstab.example
94 # which you can rename to /mnt/etc/fstab.
96 mv /mnt/etc/fstab.example /mnt/etc/fstab
99 Once you've duplicated the CD onto your HD you have to make some edits
100 so the system boots properly from your HD. Primarily you must remove
101 or edit /mnt/boot/loader.conf
103 # Remove /mnt/boot/loader.conf so the kernel does not try to
104 # obtain the root filesystem from the CD.
106 rm /mnt/boot/loader.conf
108 At this point it should be possible to reboot. The CD may be locked
109 since it is currently mounted. Be careful of the CD drawer closing
110 on you when you open it during the reboot. Remove the CD and allow
111 the system to boot from the HD.
113 WARNING do not just hit reset, the kernel may not have written out
114 all the pending data to your HD. Either unmount the HD partitions
119 (remove CD when convenient, be careful of the CD drawer closing on you)
121 Once you have a working HD based system you can clean up /etc/rc.conf
122 to enable things like cron, sendmail, setup your networking, and so
123 forth. If 'ifconfig' does not show your networking device you could
124 try to kldload it from /modules. With a recognized network device
125 you can ifconfig its IP address or, if you have a DHCP server on your
126 network, use 'dhclient <interfacename>' to obtain an IP address from
129 USING CVSUP TO OBTAIN A CVS TREE, PORTS, AND DOING BUILDWORLDS
131 cvsup can be used to obtain the DragonFly cvs repository, the FreeBSD
132 ports tree, and so on and so forth. 'man cvsup' for more information on
133 its capabilities. cvsup is a port (not part of the base system), but
134 it IS included on the CD. The cvsup example files are in
135 /usr/share/examples/cvsup. You will primarily be interested in the
136 DragonFly CVS repository, DragonFly-supfile, and the FreeBSD ports,
137 FreeBSD-ports-supfile. Once you have done the initial cvsup of the
138 blocks of data that you want you may wish to create a cron job to
139 keep it all up to date. However, please do not run an unattended cvsup
140 more then once a day.
142 # get the CVS pository (it is placed in /home/dcvs)
143 cvsup /usr/share/examples/DragonFly-supfile
144 # install the source from the CVS hierarchy
146 cvs -R -d /home/dcvs checkout src
147 cvs -R -d /home/dcvs checkout dfports
149 # get the FreeBSD ports tree (it is directly broken out into /usr/ports)
150 cvsup -h cvsup.freebsd.org /usr/share/examples/FreeBSD-ports-supfile
152 # buildworld and installworld examples
158 # buildkernel and installkernel examples. Create your own custom kernel
159 # config in /usr/src/sys/i386/conf/<YOURKERNEL> and you can build and
160 # install custom kernels.
162 # WARNING! Always keep a fully working backup kernel in / in case
163 # you blow it. Remember that /kernel.old is overwritten when you
164 # make installkernel. It is usually a good idea to maintain an emergency
165 # kernel as /kernel.GENERIC or /kernel.bak. If all else fails you can
166 # still fall back to booting the CD.
169 make buildkernel KERNCONF=GENERIC
170 make installkernel KERNCONF=GENERIC
172 EMERGENCY RECOVERY FROM THE CD
174 Lets say you blew up your kernel or something else in / and you need to
175 boot the CD to fix it. Remember that you have a fully operational
176 system when booting the CD, but that you have to fsck and mount your
177 hard drive (typically onto /mnt) to get at the contents of your HD.
179 Your HD is typically an IDE hard drive, so the device is typically
180 /dev/ad0. DragonFly is typically on the first slice, which is
181 /dev/ad0s1, and the root partition is always in partition 'a',
182 which is /dev/ad0s1a.
184 # fsck root before trying to mount it.
186 # mount root read-write onto /mnt
187 mount /dev/ad0s1a /mnt
188 # copy files from the CD as appropriate to make it possible to boot
189 # from your HD again. Note that /mnt/kernel may be flags-protected.
190 chflags noschg /mnt/kernel
191 cp /kernel /mnt/kernel
192 cp /modules/* /mnt/modules/
194 If you want to mount other partitions from your HD but have forgotten
195 what they are, simply cat /mnt/etc/fstab after mounting the root
