Public bug reported:
I'm running Wily Beta 2, updated to the latest packages in the wily
repository, with autofs-ldap using mounts stored in LDAP. On startup
systemd immediately puts autofs into a failed state as it segfaults when
reading the auto.master.
Autofs & autofs-ldap version is 5.1.1-1ubuntu2.
The log in journalctl looks like this:
