Description of problem:
upgrade to fedora 28, log into gnome and try to use things.
SELinux is preventing systemd from 'create' accesses on the unix_stream_socket Unknown.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that systemd should be allowed create access on the Unknown unix_stream_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'systemd' --raw | audit2allow -M my-systemd
# semodule -X 300 -i my-systemd.pp
