[Pkg-cryptsetup-devel] Bug#488842: no integration with lvm in initramfs

[martin f krafft]

Package: cryptsetup
Version: 2:1.0.6-2
Severity: normal
File: /usr/share/initramfs-tools/scripts/local-top/cryptroot

On a standard d-i-install system, I have /dev/hda2 hold a LUKS
volume, which is made available as /dev/mapper/hda2_crypt after
decryption. /dev/mapper/hda2_crypt is a physical LVM volume, holding
the "vg0" volume group, where individual logical volumes reside.

Upon boot, /usr/share/initramfs-tools/scripts/local-top/lvm is run
before cryptroot, because cryptroot makes sure it depends on
everything else:

  prereqs()
  {
          # Make sure that cryptroot is run last in local-top
          for req in /scripts/local-top/*; do

As a result, the LVM hook, which somehow knows about vg0 and tries
to activate it, fails and prints something like

  lvm: Failed: volume group `vg0' not found

to the console just before the password prompt. This is ugly and
confusing.

After decryption, cryptroot now does the LVM stuff itself, which is
also ugly and error-prone.

Please integrate better with the lvm hook and let it take care of
LVM-related stuff when the time is ripe. Don't do LVM stuff from the
cryptroot hook.
