worked until recently. I just upgraded to Fedora 27, but I *think* this worked after the upgrade, so I don't know what's going on there.
I get nothing whatever in auditd, which is weird. In syslog I get:
Dec 25 09:48:07 jukni systemd[669]: selinux: avc: denied { status } for auid=n/a uid=1086 gid=1086 cmdline="" scontext=staff_u:staff_r:staff_t:s0-s0:c0.c1023 tcontext=staff_u:staff_r:staff_t:s0-s0:c0.c1023 tclass=system permissive=0
Further, this:
[sampre_mw@jukni ~]$ systemctl --user restart lojban_mediawiki_web Failed to restart lojban_mediawiki_web.service: Access denied See user logs and 'systemctl --user status lojban_mediawiki_web.service' for details.
Gives this in syslog:

I can't find anything in sesearch about self:system, and all I can find in https://github.com/TresysTechnology/refpolicy.git or https://github.com/TresysTechnology/refpolicy-contrib.git is:
policy/modules/kernel/kernel.te 481: allow can_load_kernmodule self:system module_load;
policy/modules/system/init.te 225: allow init_t self:system { status reboot halt reload };
It strikes me as unlikely that F27 *actually* shipped with a setup that makes systemctl user operations not work.
I don't have a comparable user to test with, really, but at first glance my other F27 systems seem OK.
Any idea what I broke?
I have confirmed that a comparable user on one of my other F27 systems works fine.
Does it seem like a relabel reboot would be worthwhile?
Also, what should the type of user unit files be?
[sampre@vrici ~]$ ls -lZ ~/.config/systemd/user/ total 8 drwxr-xr-x. 2 sampre sampre staff_u:object_r:user_home_t:s0 66 Feb 6 2017 default.target.wants -rw-rw-r--. 1 sampre sampre staff_u:object_r:user_home_t:s0 417 Jul 14 00:32 jbotcan_database.service -rw-rw-r--. 1 sampre sampre staff_u:object_r:user_home_t:s0 419 Jul 14 00:32 jbotcan_site.service
^^ that's on the system that's working, but setting it to user_home_t on the other system doesn't seem to help anything.
