Yeah...a gzip of the .iso turns out to be about 39 MB, which is in line with
what I was expecting.

The CD image burns and boots, at least as far as aboot, but attempting to
boot Linux crashes hard:

You didn't specify the type of your ufs filesystem

mount -t ufs -o ufstype=sun|sunx86|44bsd|old|hp|nextstep|netxstep-cd|openstep ...

>>>WARNING<<< Wrong ufstype may corrupt your filesystem, default is ufstype=old
ufs_read_super: bad magic number
read_super_block: can't find a reiserfs filesystem on (dev 01:00, block 64, size 1024)
read_super_block: can't find a reiserfs filesystem on (dev 01:00, block 8, size 1024)
Kernel panic: VFS: Unable to mount root fs on 01:00

This tells me that, for some reason, the system isn't recognizing the
filesystem type on /dev/ram0. This is weird, because genkernel is building
it as ext2... Do I need to include CramFS or ROMFS?
