Yes, this is also what I experienced in german locale. I meant "at
least a chance to associate" in that works at least for languages
where the translation is not as long as for dutch or german, whereas
replacing it with "crypto" would make it impossible in any case.

Using just the device name as you described seems very practical and
I think actually solves this problem. The device name is mentioned
in the humandev string of the encrypted device, so it can be asso-
ciated easily. I'm currently testing a patch like the attached which
puts string like "loop0" or "sda5_crypt" in the last column. Will
followup once I've confirmed that it works.
cheers,
Max
