Bug purposely affected to mountall, please do not reaffect this bug to cryptsetup - There's already a cryptsetup bug discussing this issue (#475936), but this issue (most probably) needs to be fixed mainly in mountall, not cryptsetup (unless the contrary can be demonstrated otherwise than silently reaffecting this bug back to cryptsetup...)
