Connect your device and find out the UUID of the filesystem by running either blkid or lsblk -f.

Add a line to /etc/fstab such as:

UUID=05C5-A73A /mnt/32GBkey vfat noauto,nofail,x-systemd.automount,x-systemd.idle-timeout=2,x-systemd.device-timeout=2

Then execute:

systemctl daemon-reload && systemctl restart local-fs.target

Explanation:

noauto - don't mount with mount -a

nofail - boot will continue even if this mount point is not mounted successfully

x-systemd.automount tell systemd to automount this etnry

x-systemd.idle-timeout=2 - wait 2 seconds before unmounting the device after last usage

x-systemd.device-timeout=2 - wait only 2 seconds before giving No such device if the device is not connected

Note:

There are no quotes around the UUID number.

The mount point directory doesn't need to exist - it will be created

For more information about the options available, see systemd.mount(5)

Is there any advantage to this over a udev rule? This seems very specific for a single device (given the UUID-dependency of fstab), where a udev rule could cover e.g. any USB flash drive.

/etc/fstab doesn't have the dependency you assert, accepting LABEL=..., PARTLABEL=... and good old /dev/usbkey. You could always setup a udev rule to make /dev/usbkey, but I don't know how to mount using udev alone.
