Title:
  systemd-fsck laps 30s on boot for /dev/mapper/home

Status in systemd package in Ubuntu:
  New

Bug description:
  Using 15.04 beta 2 witht the following setup:
  /dev/sda is a SSD (crucial mx100) in main SATA port of Inspiron 15 3521
  /dev/sdb is a hdd in an hdd caddy in sata original dvd drive bay

  root is /dev/sda4 on SSD
  /dev/sda5 is a caching bcache partition (on SSD) for the /dev/sdb5 bcache backing LUKS home partition

  /etc/crypttab:
  home        /dev/bcache0         /root/.xxxxxxxxx-64bd-44ca-a46e-xxxxxxxxxx.bin     luks

  For an unknown reason, during boot, systemd-fsck laps 30s for doing a fsck on /dev/mapper/home.
  But the fsck is not really run, it should return immediatly

  $ systemd-analyze blame|head -3
