I can confirm this bug is still present. My /etc/crypttab is correct, verified with 'cryptdisks_start bobfred' My /etc/fstab is correct, can mount /dev/mapper/bobfred on /bobfred
On boot systemd handles my LUKS root partition correctly. bobfred is where systemd gets stuck. It prompts for a password, gets that right and can see the filesystem then loops infinitely with 'a start job' nonsense - it doesn't know what to do next. Please abandon systemd, if that is not an option a bugfix would be nice. Thanks James
