Here's your problem.  By the way, using the -V command line option to
catalyst when building would have shown you where the problem package
lies.  Also, the spec file you're basing this off of is *very* old if it
still has kudzu in there.  I would suggest finding something a little
less dated.  Try USE="doc examples" emerge catalyst.

Without USE="X" then livecd-tools does not install mkxf86config (or
x-setup, for that matter).

If you want proper X support, you are *required* to use USE="X", unless
you come up with your own method of X auto-detection.

I'd use a fsscript to sed the gdm.conf file and rc.conf.  At least,
that's what I did for the 2005.1 Installer LiveCD.

Yes.

This is documented in the example specs installed when using USE="doc".
The specs installed when using USE="examples" are the specs used to
build 2005.0's release.

Yes.

The solution above is the best solution.

The script gets executed when building your CD, not after X is
configured.  There is nothing that is executed at boot, rather than at
build-time configured via catalyst.

livecd/rcdel: pwgen *and* fsscript

You could also remove pwgen from yout livecd-stage1 spec file.

Yes.

The preferred method is to just edit the ebuild itself in your portage
directory before making your snapshot, though.  Be sure to run ebuild
<ebuildname> digest from the ebuild's directory, though!

No.  You could try using a root_overlay with your
own /etc/conf.d/local.start, but I recommend that you copy the one that
ships with catalyst as a basis, and append to it, rather than making
your own.  You can find it under /usr/lib/catalyst/livecd/files as
livecd-local.start.

Good luck.
