[pkg-cryptsetup-devel] Bug#704007: cryptsetup: make mountpoint used by passdev configurable

[schaarsc at gmx.de]

Package: cryptsetup
Version: 2:1.4.3-4
Severity: normal

passdev has hard coded the mount point (/tmp/passdev.XXXXXX). To cope with
the following scenario the mount point should be configurable:
 - /     is on encrypted deviceA
 - var is on encrypted deviceB 
 - /tmp is a symlink to /var/tmp
 
mount operation for / works, I suspect because initram is still using a
tmpfs at this point in time.

mount operation for /var fails because passdev is trying to create
mount point /tmp/passdev.XXXX, but /tmp/->/var/tmp does not exist, yet.

workaround: replace /tmp with /run (my /run is a tmpfs) in 
/lib/cryptsetup/scripts/passdev
