Can't gracefully close rclone mount

[Animosity022]

Yes, again, sorry for trying to help you out here as I'm a glutton for it as I continue forward as you continue to insult me over and over.

I have no issues as fusermount returns properly with no IO going on:

I used to use KillMode=none to avoid the sigterm but that's being deprecated soon as I spent quite some time avoiding SIGTERMs for a mount because it tends to leave things in a bad state as system will SIGTERM first, that won't work and it'll SIGKILL leaving it in a bad state.

@Summertime

and out of genuinely trying to be helpful, you might want to check your journal while stopping your service:

Those were actually suggested by another rcloner not me as I don't use it.

My service is here but this one still has KillMode=none for now until it does actually get deprecated:

homescripts/rclone-movies.service at master · animosity22/homescripts (github.com)

Good luck.

I did not intend to insult, I'm sorry for that.

I'm assuming you know why killmode=none is a problem, I'd recommend using a program that uses pidfd_open on $MAINPID (noting that systemd docs tell you off for using $MAINPID for this reasons) and then following it with unmounting and then polling the fd acquired earlier.

An untested solution, orphaning an entire service to be potentially SIGthecomputershutsdown if there is a active fd, or writing C code just to close a service without a exit code, I do not find any to be tenable.
