[CentOS] systemd, oh my

Ok, folks, I don't get this one at all.

I've got a server that I just rebuilt last week, from C5 to C7. It used to
export filesystems. Those were moved to another server, and NFS wasn't
turned up when I built it. I just turned it down again. And yet, I see
Mar 14 10:26:33 <servername> systemd: Job
dev-disk-by\x2dlabel-export1.device/start timed out.
Mar 14 10:26:33 <servername> systemd: Timed out waiting for device
dev-disk-by\x2dlabel-export1.device.
Mar 14 10:26:33 <servername> systemd: Dependency failed for File System
Check on /dev/disk/by-label/export1.
Mar 14 10:26:33 <servername> systemd: Dependency failed for /export/1.

Why is this running? The systems' been up for 10 days, and I didn't set up
such a job.
