Debian Installation :: Systemd - Automount Windows Partition / USB Devices In Jessie

There seems to be no documentation on how to automount partitions and USB devices under systemd in Jessie. (Overall, systemd entirely lacks any useful documentation or GUI configuration tools -- all very cryptic and hidden.)

I created custom files to enable automounting. I put them in /etc/systemd/system -- this may not be the right place, but it works.

Kernel note:
This does not work under the old Wheezy kernel linux-image-3.2.0-4.

To automount my Windows partition so I can access its files, I created:
/etc/systemd/system/media-windows.mount

The name of the file must match the mount point -- in this case, /media/windows

My file notes the device and file type, plus an fmask option so all the Windows files don't seem to be executable:

[Unit]
Description = windows mount to /media/windows
[Mount]
What=/dev/sda1
Where=/media/windows
Type=ntfs-3g
Options=fmask=111
[Install]
WantedBy=multi-user.target

The file ownership must be root.root. Apparently it doesn't need to be executable.

After creating, enable with:

sudo systemctl enable media-windows.mount

and it will mount on the next boot.

I read elsewhere that the before running the enable command you should run a start command:

sudo systemctl start media-windows.mount

but that didn't work for me.
