It's worth noting that the "correct" way to do this is now with fs
labels or UUIDs.  Personally, I use LVM for everything but
boot/root/swap, and that uses UUIDs internally, so I don't have much
issue (it would be sweet if Gentoo could easily boot from LVM, but that
requires an initrd).

Anyway, I'm not too sure how to indicate a UUID to the kernel for its
root fs.  There's a RedHat kernel patch that allows you to specify e.g.,
'root=LABEL=myroot' on the kernel cmdline, but I'm not sure if that's
available in the stock Gentoo kernel, or if it supports UUIDs.

You can use 'LABEL=foo' or UUID='fooo-ooo-ooo..' in /etc/fstab, though.
