Link unit file

$ systemctl link [path/to/unit.service]

$ systemctl link [path/to/unit1.service path/to/unit2.service ...]

systemctl link PATH...

systemctl link creates a symbolic link in the unit file search path pointing to a unit file located elsewhere. This makes the unit available to systemd commands without copying the file.
The link is created in `/etc/systemd/system/` (or the user equivalent with `--user`). The original file must be an absolute path.

The linked file must remain in place; removing it breaks the link. Use `systemctl disable` to remove the link. The linked unit is not automatically enabled; use `systemctl enable` after linking to start at boot.

The link subcommand allows testing or using unit files stored outside standard locations, useful during development or when unit files are managed by external configuration management systems.
