 See http://www.knoppix.net/ for an example.  Also check:

 Macs can boot from CDs, so yeah, it's possible.  (GNU/Linux runs fine on
Macs, even some m68k I think!  Old PPCs (with NuBus instead of PCI) are a
problem, though.  Motorola had a version of Linux running on top of Mach,
but I don't think it's very up to date anymore.

 I went looking, and I actually found one: http://www.gentoo.org/ has live
CD images for x86, Mac, and SPARC[1].
is their "master mirror", so there are probably copies in other places.
I think they mean "live CD" in the sense that you can boot and use GNU/Linux
without touching your hard drive.

 As for customizing the contents, I don't know.  Unless the people who make
these have something specially set up for doing it, you could just get a
system set up in a 650MB partition (or a file mounted with the loopback
device), and put the ext2 FS right onto the CD.  You could also convert it
to iso9660 with RockRidge.  I guess you could download the ISO image and
change what's in it before you burned it.  I don't think ISO9660 can't be
mounted read-write, so it would have to do more than mount it through the
loopback device and cp files into it :(

[1] actually, it doesn't look like there any CD images for SPARC, too bad
