I've put together a few scripts to help set this up. I've been
happily using this setup for about a year or so. These are at:
http://people.freebsd.org/~bsd/cdroot/
These scripts create an image that can be burned on to a CD and then
booted from. I've also got hooks in there so that if you have a
floppy disk present with a /etc on it, it will be used to override
files in the system /etc. This allows one to use the same CD for many
applications and have per-system customizations come off the floppy.
For example, I've put together firewalls that use this and the
hostname, firewall rules, etc, are copied from the floppy.
Also, I've written a simple installer script that gets dropped at
/etc/inst on the CD. If you build a FreeBSD release and copy disc1 of
that release to /dist on the CD, the installer script can be used to
install onto a new system. It's nowhere near a full sysinstall
replacement, but it does what I want with minimal questions.
There are a few minor issues that I need to fix, mainly that I have
ksh installed in /bin/ksh and that is used by the scripts, which ends
up biting people. I keep meaning to clean that up and use /bin/sh
solely. However, I use ksh for its array handling and I need to
convert those to the really hokey method of doing arrays in /bin/sh.
