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. > -----Original Message----- > From: systemd-devel <systemd-devel-bounces@xxxxxxxxxxxxxxxxxxxxx> On > Behalf Of Windl, Ulrich > Sent: Tuesday, July 30, 2024 10:26 AM > To: Andrei Borzenkov <arvidjaar@xxxxxxxxx>; Mantas Mikulėnas > <grawity@xxxxxxxxx> > Cc: systemd-devel@xxxxxxxxxxxxxxxxxxxxx > Subject: [EXT] Re: Re: "OnUnitInactiveSec Timer not firing" > issue > > > > > -----Original Message----- > > From: Andrei Borzenkov <arvidjaar@xxxxxxxxx> > > Sent: Monday, July 29, 2024 1:19 PM > > To: Mantas Mikulėnas <grawity@xxxxxxxxx> > > Cc: Windl, Ulrich <u.windl@xxxxxx>; systemd-devel@xxxxxxxxxxxxxxxxxxxxx > > Subject: [EXT] Re: "OnUnitInactiveSec Timer not firing" > issue > > > > On Mon, Jul 29, 2024 at 2:12 PM Mantas Mikulėnas <grawity@xxxxxxxxx> > > wrote: > > > > >> > > >> Furthermore it seems to be necessary to run the service unit itself, too > > (assuming it must be enabled also, right?) > > > > > > > > > No. The purpose of the timer is to start the service, so starting the service > > manually (or "enabling" it, to be started on boot) would be redundant. > > > > > > > OnUnitInactiveSec begins counting when service gets stopped.
