So I wanted to setup automatic mounting (read as autofs) with systemd, without using
Unfortunately, the man page didn’t have any examples so it wasn’t that easy to figure out. Luckily there is an excellent guide at RHCSA course .
You need two files
- First one to setup the mount itself.
- Second to perform automatic mounting.
It’s not that easy to name the file for automatic mounting. Quote from manpage:
Automount units must be named after the automount directories they control. Example: the automount point /home/lennart must be configured in a unit file home-lennart.automount. For details about the escaping logic used to convert a file system path to a unit name see systemd.unit(5).
Content of the files
$ cat /etc/systemd/system/mnt-scratch.automount [Unit] Description=Automount Scratch [Automount] Where=/mnt/scratch [Install] WantedBy=multi-user.target $ cat /etc/systemd/system/mnt-scratch.mount [Unit] Description=Scratch [Mount] What=nfs.example.com:/export/scratch Where=/mnt/scratch Type=nfs [Install] WantedBy=multi-user.target
Now to notify systemd there are some new files available:
$ systemctl daemon-reload
Feel free to disable the
