The chroot is currently doing an emerge -e @world so I've shelled into
the machine and am showing from that perspective. All the typical fsck
programs are there and I rebuilt e2fsprogs a couple of days ago.


livecd gentoo # ls /mnt/gentoo/sbin/fsck*
fsck          fsck.ext2     fsck.ext4     fsck.minix
fsck.cramfs   fsck.ext3     fsck.ext4dev
livecd gentoo #

When emerge -e @world completes I'll give it a reboot but somehow I
don't have much faith that it will have fixed anything. Right now I
feel it's either something missing from my kernel config, or some
critical install step that I keep missing because of the way I read
the document and maybe some step that listed inside a paragraph
instead of being called out in purple like most of them are. (They are
in there, like the locale-gen step and a few others...)

I'll check back later when the rebuild is complete.

Thanks!

Cheers,
Mark
