Title:
  8.10 alternate installer breaks in multiple ways with raid/luks/lvm

Status in “debian-installer” package in Ubuntu:
  Confirmed

Bug description:
  So. I tried to do an install of 8.10 on a mirrored encrypted lvm, with
  /boot on a separate mirror. With the alternate installer of course,
  since it's funky stuff.

  First thing I noticed was that the partitioning tool forgets that I
  said to use the /boot mirror as /boot every time I do some luks and
  lvm setup. No biggie, just a reinstall with me reminding the installer
  of this at the end. Yay. Success. Or is it?

  No. The system doesn't boot but tosses me into the initrd shell
  prompt. With no query of the LUKS password at all. So it doesn't even
  seem to try to set up LUKS at all.

  'course, after I cryptsetup manually, I do get my md1_crypt. But wait,
  it isn't the lvm physical volume. Turns out the installer creates a
  "partition" (!) on the md1_crypt volume called md1_cryptp1 and
  installs there. I lose interest in finding the correct magic
  (presumably dmsetup is involved) to set that up even manually. This
  may be related to Debian bug 494910. Except it was really well hidden
  in the Ubuntu installer, didn't complain. Just asked to create a
  partition. I didn't think much of it since it asked that in the
  previous release as well. It just didn't actually, you know make it,
  so I figured it's just a silly partman internal thing where it has to
  think everything has partitions in it.

  Sooyeah. In the future, you know, it'd probably cover quite a few
  installation failure scenarios if you'd just see if a raid/luks/lvm
  install manages to boot.

  Meanwhile, I'll ponder about doing a fresh 8.04 and then upgrading, or
  switching to Debian unstable...
