boot gentoo-basic-x86-1.4_rc2.iso entirely into tmpfs?

[dws]

Is there any option to boot gentoo-basic-x86-1.4_rc2.iso
entirely into tmpfs instead of using cloop?

I find cloop to be quite inconvenient, at least of the basic CD with 40MB.
I don't think it's worth the trouble just for a 27 MB cloop file. It's OK for
things like KNOPPIX, where you have to fit an entire live filesystem onto
a single CD.

root@cheetah:pts/1 /export # ls -l /mnt/cdrom/livecd.cloop
-rw-r--r-- 1 1008 users 28321920 Jan 1 07:25 /mnt/cdrom/livecd.cloop

All my bigger computers have at least 1 Gig of RAM, and even the smaller
ones have 256-512 MB. Should be plenty to load everything into tmpfs.
