systemd transient units

You can create units on-the-go with systemd-run. Very useful for quickly creating and scheduling one-off services. This tool mainly involves systemd services and systemd timers.

Like most systemd-related binaries, this can be run at system- and user-level (see systemd at user-level).

# This will create a user-level service file with the given command as the task.
systemd-run --user borgmatic --config emergency-config.yaml --verbose

# Create a transient timer for the service.
systemd-run --user borg-backup@external-drive.service --on-calendar=12:00

The result should give you the generated name of the unit. Then, they can be managed like an ordinary unit. Unit generated this way will persist until the next boot. If you want to manage them on a permanent basis, create the appropriate unit files for them.
