Title:
  initramfs should try password against other devices

Status in “cryptsetup” package in Ubuntu:
  Confirmed

Bug description:
  Due to multiple drives I have multiple encrypted volumes.  The
  passphrase for all of them is identical.. However at boot I am asked
  the password for each one, and have to type the same thing over and
  over again.  cryptsetup during boot should at least try the previously
  typed in password against each volume.
