the user service DOES work on EL and clones, here is how

[mailinglists35]

contrary to documentation I am able to start the user service on OL9
the thing is you have to enter the user that runs/owns the files via machinectl instead of sudo/su/runuser/pkexec (a trick learned from podman to correctly enter the environment to interact with it) and enable linger for that user before that

$ sudo loginctl enable-linger onedrive
$ sudo machinectl shell onedrive@ /bin/bash -li

$ cp /lib/systemd/system/onedrive.service .config/systemd/user/
$ systemctl --user enable onedrive
Created symlink /home/onedrive/.config/systemd/user/default.target.wants/onedrive.service → /home/onedrive/.config/systemd/user/onedrive.service.
$ systemctl --user start onedrive
$ systemctl --user status onedrive.service

journalctl will NOT work via machinectl one liner, you would have to enter the shell first via machinectl - or - hack via systemd-run:

$ sudo systemd-run --machine=onedrive@ --quiet --user --collect --pipe --wait bash -c 'journalctl -S today --no-pager --no-hostname --user -f'

what is annoying but not putting resources into find out why, is that on OL9:

• it works in regular shell by starting it from command line
• it works as that user's service
• it always fails to start if registered in system service as onedrive@that_user, with:
