+Quick guide on how to make a custom Solaris boot CD to use as a Bacula
+client rescue CD for Solaris 10_03/05 x86 (FCS).

+
+What you will need:
+ 1) Static compiled file daemon and config files for your setup.
+ 2) Solaris 10_03/05 CD 1 of 4
+ 3) CD Burner
+ 4) super-user access to build the miniroot & iso image.
+
+
+1) mkdir /tmp/isodir
+
+2) Create an empty file to hold the miniroot plus a little extra room
+ and leaves about 290mb free on the CD
+
+ # mkfile 360m /var/tmp/miniroot
+
+3) Map the file to a block device
+
+ # lofiadm -a /var/tmp/miniroot
+ /dev/lofi/1
+
+4) Create a new file system on the miniroot
+
+ # newfs -i 8192 -m 1 /dev/rlofi/1
+
+ newfs: construct a new file system /dev/rlofi/1: (y/n)? y
+ /dev/rlofi/1: 736800 sectors in 1228 cylinders of 1 tracks, 600 sectors
+ 359.8MB in 77 cyl groups (16 c/g, 4.69MB/g, 576 i/g)
+ super-block backups (for fsck -F ufs -o b=#) at:
+ 32, 9632, 19232, 28832, 38432, 48032, 57632, 67232, 76832, 86432,
+ 643232, 652832, 662432, 672032, 681632, 691232, 700832, 710432,
+ 720032, 729632
+
+5) Mount the block device
+
+ # mount /dev/lofi/1 /mnt
+
+6) Copy the root image to the miniroot file system
+
+ # cd /cdrom/cdrom0/s0
+ # find . -depth -print | cpio -pdm /mnt
+ 780288 blocks
+
+7) Add your static built fd and config files to /mnt
+ I just reproduced my production directory structure so it looks
+ like this but you can place the files however you want. Just make
+ sure they match the config files.
+
+ # cd /mnt/
+
+ # ls -R opt/local
+ opt/local:
+ bin etc sbin
+
+ opt/local/bin:
+ bacula bconsole btraceback.dbx btraceback.gdb gconsole
+
+ opt/local/etc:
+ bacula
+
+ opt/local/etc/bacula:
+ bacula-ctl-fd bacula-fd.conf bconsole.conf
+
+ opt/local/sbin:
+ bacula-fd bconsole btraceback
+
+ Edit your config files so that the working directory
+ is /tmp so bacula has writable place to put the pid and state file.
+
+ I also needed to copy some gcc libs from /usr/sfw/lib to the miniroot
+ and setup a couple of softlinks. Put them in the /mnt/usr/sfw/lib
+
+ # cd /mnt/usr/sfw/lib
+ # cp /usr/sfw/lib/libgcc_s.so.1 .
+ # ln -s libgcc_s.so.1 libgcc_s.so
+ # cp /usr/sfw/lib/libstdc++.so.6.0.3 .
+ # ln -s libstdc++.so.6.0.3 libstdc++.so.6
+
+8) Unmount the file system and delete the lofi device
+
+ # umount /mnt
+ # lofiadm -d /dev/lofi/1
+
+9) Extract the boot files from the CD
+
+ a) Turn off the volume manager
+ # /etc/init.d/volmgt stop
+ b) The CD should stll be in the drive. Make sure you use the correct
+ device for your CDROM drive
+
+ # dd if=/dev/dsk/c1t0d0p0 of=/tmp/mboot+pboot.cd bs=512 count=2
+ 2+0 records in
+ 2+0 records out
+
+ c) Save the bootblk into a file named bootblk.cd
+
+ # dd if=/dev/dsk/c1t0d0p0 of=/tmp/bootblk.cd bs=512 iseek=4 count=60
+ 60+0 records in
+ 60+0 records out
+
+10) Create the boot files
+
+ a) Create the bootimage
+
+ # cp /tmp/mboot+pboot.cd /tmp/isodir/.bootimage
+
+ b) Create the boot file with a 1k gap in the file
+
+ # cp /tmp/mboot+pboot.cd /tmp/genboot
+ # dd if=/dev/zero bs=1024 count=1 >> /tmp/genboot
+ 1+0 records in
+ 1+0 records out
+ # cat /tmp/bootblk.cd >> /tmp/genboot
+
+11) Add your custom content to the CD image (max size is about 290mb)
+
+ I haven't messed with this yet but you should be able to place
+ just about anything you want in the /tmp/isodir before you create
+ iso image. It would be a good place to put config files for other
+ systems. Whatever program you run has to fit in available memory.
+
+12) Create the CD image using mkisofs
+
+ # mkisofs -r -no-emul-boot \
+ -b .bootimage \
+ -c .catalog \
+ -G genboot \
+ -o bacula-rescue.iso \
+ -sunx86-boot /var/tmp/miniroot \
+ /tmp/isodir/
+
+ Size of boot image is 4 sectors -> No emulation
+ Total translation table size: 2048
+ Total rockridge attributes bytes: 331
+ Total directory bytes: 0
+ Path table size(bytes): 10
+ Total extents including Solaris x86 boot = 184480
+ Max brk space used 8000
+ 184630 extents written (360 MB)
+
+13) Create the custom boot CD
+
+ a) Restart volmgt
+
+ # /etc/init.d/volmgt start
+ volume management starting.
+
+ b) Burn the image (use the correct device for your burner).
+ You can get the correct device with:
+
+ # /opt/sfw/bin/cdrecord -scanbus
+
+ Burn the image with:
+
+ # /opt/sfw/bin/cdrecord dev=1,0,0 -v -eject /tmp/bacula-rescue.iso
+
+14) Now your ready to boot the the system with the rescue CD
+
+ a) Insert the rescue CD and boot the system.
+ b) Choose option 4 Solaris Interactive Text (Console session)
+ c) Allow the install routine continue and setup the networking
+ information according to your site.
+ d) When you see the "Solaris Interactive Installation" screen exit
+ the install routine with F5 then confirm with F2
+ e) Format and partition the new hard drive (duplicate the partitioning
+ scheme that was used on the old HD).
+ f) Create the file systems with newfs, check them with fsck.
+ g) Mount the HD to /mnt
+ h) Start the bacula file daemon with:
+ /opt/local/bin/bacula start
+ and then bconsole with:
+ /opt/local/bin/bconsole
+
+ You should now be connected to you backup server and ready to
+ restore your system to /mnt
+ i) After the restore is complete you need to make the new HD bootable
+ with installboot (details on how to do this in the next rev of the doc)
+ For reference (man installboot)
+ j) reboot
