 * cryptsetup:
   - cryptsetup-generator: warn if the password files are world-readable
-  - cryptsetup-generator: add RequiresMountsFor= to cryptseup service files referencing a file, similar for devices
   - cryptsetup-generator: allow specification of passwords in crypttab itself
   - move cryptsetup key caching into kernel keyctl?
