Title:
  keyscript option in crypttab not implemented

Status in systemd package in Ubuntu:
  Triaged
Status in systemd package in Debian:
  Confirmed

Bug description:
  The setup for unlocking an encrypted volume during boot using (only) a
  keyfile (on a detachable USB drive) usually calls for a keyscript to
  be specified as one of the encrypted volume's options. But with
  systemd, such encrypted volumes can only be unlocked during boot by
  typing in a passphrase.

  Steps to reproduce:
  1. Have a LUKS encrypted volume.
  2. Have said volume specified in /etc/crypttab, with keyscript= option pointing to your script for outputting the unlocking key.
  3. Boot.

  What I expect to happen:
  To have the volume unlocked by the script at boot time without manual intervention.

  What happens instead:
  Plymouth shows a prompt to enter a valid passphrase for the volume.

  Workarounds:
  Apparently the options for unlocking encrypted drives, including keyscript, can also be specified at the kernel command-line, without crypttab, and according to yaantc at Hacker News [1] this can be used to work around the issue. I haven't personally tried this.
