Actually, I was wrong, it's not because of DNS problems, it's because systemd is trying to mount the filesystems before the network is up. I changed the host names in /etc/fstab to IP addresses, and it still doesn't work:
Jan 20 08:17:31 jik5 mount[979]: mount error(101): Network is unreachable
So there is something here that is definitely not working properly.
