[systemd-devel] [EXT] Re: Re: "OnUnitInactiveSec Timer not firing" issue

[Windl, Ulrich]

Hi!

Top-posting this time:
Reading the manual carefully, I recognized an asymmetry:
OnActiveSec= defines a timer relative to the moment the timer itself is activated.
OnUnitInactiveSec= defines a timer relative to when the unit the timer is activating was last deactivated.

Also the manual des not state WHERE that state is remembered.
