Public bug reported:
When attempting to acccess an existing (working) LUKS partition from the
LiveCD environment, cryptsetup fails silently. No exceptions are thrown,
no errors displayed. The LUKS device remains completely inaccessible.
I've attached an strace with the following two commands, "cryptsetup
luksDump /dev/sda3", and "cryptsetup luksOpen /dev/sda3 crypted" as
there was nothing in the logs that clearly point to a problem other than
the expected result being missing.
