initrd sucks.

- you have to keep it manually up to date when the contained
  software changes, even though it's conceptually associated with
  the kernel, not that software (admittedly scripting this is
  not hard)
- it's a separate file, so it easily gets out of synch with
  the kernel it's associated with
- if the contained software changes you have to keep it up
  to date
- pivot_root is a frankly insane kludge

initramfs is much *much* nicer. I'm booting off one of those (boot in
RAID1+LVM, almost everything else in RAID5+LVM) without the slightest
qualm. (Well, without very many qualms. Not big ones anyway.)

(The boot disk is a uClibc+busybox installation, of course.)
