'systemctl disable --runtime' would disable a unit, but only if it was enabled with '--runtime', and silently do nothing if the unit was enabled persistently. And similarly 'systemctl disable' would do nothing if the unit was enabled in /run. This just doesn't seem useful. This pathch changes enable/disable and mask/unmask to be asymmetrical. enable and mask create symlinks in /etc or /run, depending on whether --runtime was specified. disable and unmask remove symlinks from both locations. --runtime cannot be specified for the disable and unmask verbs. The advantage is that 'disable' now means that the unit is disabled, period. And similarly for 'unmask', all masks are removed. Similarly for preset and preset-all, they now cannot be called with --runtime, and are asymmetrical: when they enable a unit, symlinks are created in /etc. When they disable a unit, all symlinks are nuked. $ systemctl --root=/ enable bluetooth Created symlink /etc/systemd/system/dbus-org.bluez.service → /usr/lib/systemd/system/bluetooth.service.
