[Pkg-cryptsetup-devel] Bug#446674: cryptsetup: Options "offset" and "skip" missing in /etc/crypttab

[Marc-Jano Knopp]

Package: cryptsetup
Version: 2:1.0.5-1
Severity: normal
Tags: patch

The options

  --offset, -o

and

  --skip, -b

are not supported in /etc/crypttab, which makes it impossible to automatically
decrypt an encrypted disk using either of these options.

The appended patch adds these options and at least works with the option
"offset" in /etc/crypttab. I haven't tested option "skip".

The two new options need to be mentioned in the manual page, of course.
