#2381 PR `merged`: Error out when LUKS version 2 is used (issue #2204)¶

Labels: fixed / solved / done, minor bug

Type: Minor Bug Fix
It is a minor bug when "rear mkrescue/mkbackup" does not error out
when things have actually failed.
In this case when gathering crypt information was not successful
the code blindly proceeds resulting wrong (incomplete) entries
in disklayout.conf that let later (when it is too late) "rear recover" fail.
Impact: High

How was this pull request tested?
By me on my current homeoffice laptop that uses LUKS 1.
I get still same 'crypt' entries in disklayout conf.
Brief description of the changes in this pull request:
Error out during "rear mkrescue/mkbackup" when LUKS version 2 is used
because currently LUKS version 2 is not suppported.
When LUKS version 2 is used it fails at least to determine the hash value cf.
https://github.com/rear/rear/issues/2204#issuecomment-520254591
so we use an empty hash value as a simple test if gathering crypt information
was successful and error out if not.

If there are no objections I would like to merge it today afternoon.
