What was the mount path that failed or better yet can you boot with "systemd.log_level=debug" without that hd on the kernel command line and then attach the output of the command "journalctl -b" along with that /etc/fstab so we can properly map what's happening

Comment 2 Michal Schmidt 2013-07-19 06:36:48 UTC

This is expected behaviour. systemd does not know with mounts are essential to the system's integrity and which aren't, so it goes into fail-safe (ie. the emergency mode). You can however mark non-essential mounts with the "nofail" option to avoid it.
