[toc]
Systemd can be used to mount filesystems not only on boot (simple .mount file), but also on request by any process. (.automount file)
Mount file
The .mount file should be placed in /etc/systemd/system
NOTE: The filename must be (mountpoint).mount with slashes / being replaced with dashes -
Example: /mnt/target --> mnt-target.mount
Here's an example .mount file for a CIFS share
[Unit]
Description=cifs mount
[Mount]
What=//(url/ip)/(sharename)
Where=/(target mountpoint)
Type=cifs
Options=defaults,username=(user),password=(password),file_mode=0640,dir_mode=0750,iocharset=utf8,uid=(local uid),gid=(local gid)
[Install]
WantedBy=multi-user.target
Automount file
The corresponding .automount file needs to have the same name as its .mount file
Example: mnt-target.mount and mnt-target.automount
[Unit]
Description=cifs automount
[Automount]
Where=/(target mountpoint)
[Install]
WantedBy=multi-user.target
Enable the .automount file to mount the filesystem when necessary
# systemctl enable (target-mount).automount
Service - require mount
Other services that depend on the filesystem being mounted might have issues with the built-in automounting.
In these cases, the option RequiresMountsFor= can be set under the [Unit] configuration to ensure a path is mounted.
Paths are space separated
