Well, now it's failing to mount on boot:

# systemctl status mnt-backup.mount -l
mnt-backup.mount - /mnt/backup
   Loaded: loaded (/etc/fstab)
   Active: failed (Result: exit-code) since Mon 2013-10-14 15:01:58 MDT;
2 days ago
    Where: /mnt/backup
     What: nas:/backup

Oct 14 15:01:58 office mount[1403]: mount.nfs: mount system call failed
Oct 14 15:01:58 office systemd[1]: mnt-backup.mount mount process
exited, code=exited status=32
Oct 14 15:01:58 office systemd[1]: Failed to mount /mnt/backup.
Oct 14 15:01:58 office systemd[1]: Unit mnt-backup.mount entered failed
state.

I'll probably wait to reproduce it succeeding at boot before filing a BZ
about failing at shutdown...
