Ubuntu 15.10, I have several CIFS filesystems listed in /etc/fstab.
They don't mount at boot. If I list them by host name in /etc/fstab, mount says name resolution failed in the boot logs. If I list them by IP address, mount says the network is unreachable in the boot logs.
If fixed this by adding the following in /etc/systemd/system/remote-fs-pre.target.d/override.conf:
[Unit]
Requires=NetworkManager-wait-online.service
After=NetworkManager-wait-online.service
See also #1313513. This is a problem in older, pre-systemd versions of Ubuntu as well.
