curious service files installed on fresh f34 system

[Tom Horsley]

Just been comparing my f33 and f34 partitions, and while every
other service file in the universe lives in /usr/lib/systemd/system
the two new services dbus-org.freedesktop.oom1.service and
dbus-org.freedesktop.resolve1.service are not installed there.

They appear to be in

/etc/systemd/system/dbus-org.freedesktop.oom1.service
/usr/share/dbus-1/system-services/org.freedesktop.oom1.service
/etc/systemd/system/dbus-org.freedesktop.resolve1.service
/usr/share/dbus-1/system-services/org.freedesktop.resolve1.service

The /etc files are symlinks to other services in the "normal"
place, but with a different name (oom rather than oom1)

Does anyone know what all this convolution is about?

I thought the /etc directories were where system administrators were
supposed to install copies to override the system files, why are
things installed there by fedora?

Just curious after my scripts to list info about new services failed
because the file wasn't found where I expected it :-).

Overrides go in /etc, so I suspect that these are Fedora specific
differences from upstream.

Curiously I don't have
/etc/systemd/system/dbus-org.freedesktop.oom1.service - it was clean
installed prior to beta though and there were changes with both oomd
and resolved during the pre-release period.

You could ask on devel@ list to find out for sure. I'm not certain,
but I think there were were systemd 248 changes that were too big to
take into Fedora, during pre-release period, and others weren't yet
merged upstream, so I think all of this happened because of that. And
it'll likely get cleaned up once there's a 248.1 or whatever.
