I guess so.

Unrelated to the unmount failures and therefore somewhat OT:

Should you want to switch to a .mount unit, I've set up the following
in a VM (192.168.1.11 is my laptop) and rebooted.

<begin>
# systemctl cat home-th-srvtom.mount
# /etc/systemd/system/home-th-srvtom.mount
[Unit]
Before=remote-fs.target

[Mount]
What=//192.168.1.11/srvtom
Where=/home/th/srvtom
Type=cifs
Options=credentials=/home/th/.cifscreds

[Install]
WantedBy=multi-user.target

# systemctl status home-th-srvtom.mount
● home-th-srvtom.mount - /home/th/srvtom
   Loaded: loaded (/etc/systemd/system/home-th-srvtom.mount; enabled;
vendor preset: enabled)
   Active: active (mounted) since Sat 2015-03-14 15:56:47 EDT; 1min 47s ago
    Where: /home/th/srvtom
     What: //192.168.1.11/srvtom
  Process: 554 ExecMount=/bin/mount //192.168.1.11/srvtom
/home/th/srvtom -n -t cifs -o credentials=/home/th/.cifscreds
(code=exited, status=0/SUCCESS)

</end>

FTR, the samba setup on my laptop is basic:

<begin>
# cat /etc/samba/smb.conf
[global]
bind interfaces only = yes
encrypt passwords = yes
interfaces = 127.0.0.1/8 192.168.1.11/24
security = user
unix password sync = yes

[srvtom]
path = /srv/tom
browsable = yes
writable = yes
write list = th
</end>
