Boy, I wish it were that easy!

(~)>> which fsck.jfs
/sbin/fsck.jfs

Perhaps, though I'm not sure how to determine that this is the cause, nor 
how I would fix it. I have this problem on 3 different Gentoo hosts I run 
(the only 3 Gentoo hosts I have) so it's not an isolated problem on one 
machine. Granted, all were setup by me using the guides on gentoo's site, so 
if I made a mistake I probably did it 3 times. 

I was going to try the "non-genkernel" approach and see if that worked any 
differently, as the grub configuration is quite different. I have examples 
of other distributions which work fine using jfs in this situation, but 
those do not use udev and none require the same options that genkernel seems 
to. 

Anyways, thanks for the info - if there are any other bits of useful info 
let me know. I'll continue to fiddle.
