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.
