Yeah, this doesn't sound ideal.

How close do the EPEL RPM's systemd configuration files look to the ones in the NUT tree? e.g. https://github.com/networkupstools/nut/blob/v2.7.2/scripts/systemd/nut-driver.service.in

If the EPEL RPMs have a bug tracker, it might be worth pinging them about it. The "StopWhenUnneeded=no" part is odd, in my mind, although the idea is for "upsdrvctl start" to start the drivers, let them fork, then exit. (Were you running "upsdrvctl -D start" at the command line or under systemd? I would not expect the latter to work without modifications.)

There is also a proposal for reworking the NUT driver startup under systemd, in case problems crop up later, and you want to revisit this:

As I understand it, the drivers would each get their own systemd unit, so that might be easier for isolating failures.
