Bug#353286: yaird: Check the password given to cryptsetup

[Jö Fahlke]

Package: yaird
Version: 0.0.12-3
Severity: wishlist
Tags: patch

Hi!

Here is a patch which uses blkid to identify the decrypted volume
after cryptsetup did its work.  If the identification fails, it offers
to reenter the password, to ignore the identification failure and
continue anyway (in case the encrypted volume contains something blkid
can't identify) or to open a shell for debugging.

Have a nice day,
Jö.
