Or it would be, but the last initramfs it generated for me wouldn't start
my
md0 (whole-disk software RAID via mdadm) device, which is part of the
volume
group holding /. [I should try again, perhaps genkernel has gotten smart
enough to read my mdadm.conf, ala Debian, and start whole-disk software
RAID.]
Right now, I get dumped to a shell prompt inside the initramfs each time my
system boots, I then have to start my volume group manually in partial mode
to get (RO) access to the block device / is on. [I don't seem to even have
the right tools inside the initramfs to bring up whole-disk software RAID,
or
at least I haven't figured out how.] Then Gentoo tries to boot but fails
because it can't mount / as RW (lvm marks lvs in vgs started in partial
mode
as RO block devices) although it doesn't bail out quickly, so it thinks
certain services (like localmount) have started when they haven't.
I then log in as root and bring all the lvs to RW status, remount /,
restart
the 3-4 services that Gentoo thinks are up, and let it continue.
In short, my boot process is fsck'd, but I don't reboot enough to have it
really bother me. But, this thread isn't really about my troubles even if
some of my setup *is* useful as examples of why you might need an
initramfs.
[My fsck'd setup also shows how powerful the layered startup in *nix is.
Failing to find your C: drive in Windows is not really recoverable without
boot media.]
