Building a dfs CD

["Jeffrey B. Green" <jeff@kikisoso.org>]

Hi,

I finally got my dfs cd going. The package, I believe, is geared towards 
the i386 machines, also there are a couple of modifications that I 
wanted. My final cd came in under 600M, about 585M. It did finally work 
via the ofboot.b OF file. The following instructions may not be complete 
since I may have forgotten to write a few items down. However, I don't 
think I missed much. I also apologize if they are a bit cryptic in places.


- create dfs directory and iso "attempt" via the dfsbuild process
        % dfsbuild -a powerpc -c /etc/dfsbuild/dfs.cfg -w dfsbuild
        o need to not include pkgs: acpidump pnpbios-tools mdadm
- uncompress compressed directories if necessary
- remove any cached debs from the dfsbuild directories
- need to fix yaboot.conf wrt the root system references
- modify the initrd ram fs to include necessary drivers, such as for the 
cd drive:
        o Examine it by mounting it.
        o Change it by copying it over to another directory, modify, 
and recreate the ram w/ mkcramfs
        o Increase the kernel ram size (yaboot.conf) appropriately
        o Copy marker over to new initrd
        o Some changes: copied modprobe & made a link for ld.so.1, 
added drivers
        o will need to do a depmod
- separate out the boot directory from the others since it will not be 
zftree compressed.
        o create an hfs dir with the boot dir in it
        o create an apple dir with the other (uncompressed) dirs in it
- will make a multi-session disk with boot on an 'hfs' session and the 
rest on a 'apple' session.
- can reach the yaboot files on the CD from the OF prompt with: boot 
cd:,\boot\yaboot
- to add packages to the dfs base directory do a chroot to an 
uncompressed dfs directory, e.g.
        % chroot apple-dir apt-get install somepkg
        o Will need to change tmp and var/sub symlinks to point to 
actual directories
        o nb: for the following installs I had a local reprepro powerpc 
mirror that I used.
- install the xdm, xserver, xfonts, & wm (e.g. blackbox) pkgs in order 
to have a gui
        o May need to make X link in etc/X11 to usr/bin/X (server)
- install mrxvt and menu
- install any other pkgs one might like
- create hosts file in etc
- useful to make var/log writeable by moving it to opt/dfsruntime/runtimerd
        o In general this is where anything that is needed to be 
modifiable needs to be
- add a name server to resolv.conf (tho not abs. nec.)
- set password for root and export DISPLAY
- the CD can be burned by the following procedure:
# Make an hfs bootable session with the boot directory, e.g. a target 
directory with boot
# Use this cmd to make the 1st (session) iso for a cd (if after dfsbuild 
not doing it correctly)
mkisofs -o hfs_image.iso -v -v -r -part -hfs -no-desktop -map ./hfs.map 
./hfs_target >> mkisofs.out 2>&1 &
# burn it with:
cdrecord -v -multi -dev=1,0,0 hfs_image.iso

# Retrive nec. info for 2nd (session) iso with:
cdrecord -msinfo -dev=1,0,0
0,17283         # for example

# in order to save space, the uncompressed directory tree must be 
compressed via:
mkzftree -C apple_target-old apple_target_uc apple_target &

# And make it with (where the cd writer drive (e.g. /dev/scd0) can be 
subbed for the hfs iso)
# the iso of the main directory is created by:
mkisofs -o apple_image.iso -v -v -r -z -part -apple -C 0,17283 -M 
hfs_image.iso -no-desktop -map ./hfs.map ./apple_target >> mkisofs.out 
2>&1 &

# and burn it with:
cdrecord -v -dev=1,0,0 -multi apple_image.iso
