I'm already familiar with how systemd user services for units in
~/.config/systemd/user work. I recently learned about package managed
user units, which on Fedora are unit files installed by RPMs to
/usr/lib/systemd/user.

Is it possible to disable these units? When I use "systemctl --user
disable foo.socket" the package-managed user foo.socket I disabled seems
to still be enabled when I log in.

Similarly to system units, user units are located in the following
directories (ordered by ascending precedence):

/usr/lib/systemd/user/ where units provided by installed packages
/etc/systemd/user/ where system-wide user units are placed by the system
administrator

educated guess: since enable/disable is just a wish in general, use
"mask" instead "disable" which pretty sure leads to symlink
/etc/systemd/user/servicename.service to /den/null or just place a
identuical named symlink to /dev/null there

Indeed, "systemctl --user mask" creates a symlink to /dev/null which is
effective at preventing the unit from starting when I log in. Thanks, I
wasn't aware of the "mask" command.

Not really. There was a long discussion about it but I do not think
anything was done at the end.

As mentioned you can mask them, but note that it is rather more heavy
weighted - it makes it impossible to start these units even manually.
