[root tip] [How To] Use systemd to mount ANY device

Difficulty: ★☆☆☆☆ Disk device recognition Manjaro uses udev (see Arch Wiki) to load devices at boot time. The loading of devices is arbitrary and therefore you cannot predict which device will be available at a given path. But static device names do exist and you can assign specific locations to your device and thus ensure e.g. scripts will work as expected.

@Maracuja

Should i use discard? On the Arch-Wiki i read it could cause Issues? Any recommendation?

If you read carefully, I can’t quote cause its been a while since i read that page, it should tell you what file systems can cause problems with discard…

Then use the UUID to add to your

Example: for the OP how easy it is:

$ sc-cat mnt-LutrisGames.{,auto}mount | xc

# /etc/systemd/system/mnt-LutrisGames.mount
[Unit]
Description=Lutris-Gamelib
Documentation=man:systemd.mount(5)
Documentation=man:systemd.automount(5)
After=dev-disk-by\x2dlabel-Backups.device
BindsTo=dev-disk-by\x2dlabel-Backups.device
RefuseManualStart=yes
RefuseManualStop=yes

[Mount]
What=/dev/disk/by-label/Backups
Type=btrfs
Options=noatime,subvol=/@LutrisGames

# /etc/systemd/system/mnt-LutrisGames.automount
[Unit]
Description=Lutris-Gamelib
Documentation=man:systemd.mount(5)
Documentation=man:systemd.automount(5)
PartOf=Gameing-Mounts.service

[Automount]
TimeoutIdleSec=5min

# Autostarted by Gameing-Mounts.service
# [Install]
# WantedBy=graphical.target

The above uses Filesystem LABEL but you can use UUID’s also ofcourse.
Plus the above is started using a service that pulls in other automount units also, just to make it easy to start/stop related mounts for gaming in my example…
