[pkg-cryptsetup-devel] Bug#755074: cryptsetup: Also, cryptsetup's boot-time script fails to mount a LUKS home filesystem

[Kalle Sandström]

Package: cryptsetup
Version: 2:1.6.6-1
Followup-For: Bug #755074

Dear Maintainer,

In addition to the bug reported above, which I can confirm, cryptsetup's
boot-time scripts fail to mount the encrypted /home filesystem, defined below.
Instead a /dev/mapper/pigdog0-home_crypt_unformatted is left behind, and later
scripts (obviously) fail to fsck and mount /home from its correct device node.

The problem appeared with a recent (within the last two months) upgrade from
testing. The affected system is being kept systemd-free, if that matters.

Included fstab was redacted to omit encryption-related but non-cryptsetup
information.
