Hmm... I always just build the stuff I need for booting into my kernel
rather than as modules, but I was surprised to see that mkinitrd doesn't
seem to exist nonetheless.
Fortunately mkinitrd is just a script. You should be able to just copy
mkinitrd from another distribution (possibly requiring some edits).
Alternately emerge lvm-user and use lvmcreate_initrd. Perhaps a better
solution is the LFS mkinitrd referred to in this post:

I think the -s and -S options to emerge may be what you are looking for.

I don't think so (md needs the linux kernel), but why even try? Gentoo
wisely leaves /boot unmounted. I have two drives in my system,
/dev/hda1 is my /boot partition. I created /dev/hdb1 the same size as
/dev/hda1 and just use "dd if=/dev/hda1 of=/dev/hdb1 bs=8192b" to back
it up (while unmounted). Kind of a poor man's raid1, but more than
sufficient for backing up something that changes as rarely as /boot
(only takes a few seconds to back it up, too). [NOTE: wisest to only do
your backup immediately AFTER succesfully booting a new kernel!]
I'm in the process of putting together a disk-based backup scheme (tapes
are too much hassle, and drives are pretty cheap these days). I use LVM
for everything except /boot so I can shrink/grow on demand. (Actually,
I've still got root on /dev/hda5, but I plan to move it to a raid1
volume REAL SOON NOW... :-).
I've got drive space to burn (two 80GB drives) and wanted the
performance of raid0, but I also wanted to be able to survive a drive
failure: so I backup my raid0 volumes to (normally unmounted) raid1
volumes. 3X the drive space normally required (at least for the stuff I
backup) but, hey, it's darn fast. :-)
Once I get things set up the way I like with completely automated
backups (and successfully simulate a drive failure and recovery) I'll
post my experiences to the documentation forum.
