Description Roma Hicks 2019-11-22 19:09:23 UTC
Description of problem:
Fresh install on a Dell Latitude E6230, and upgraded the system shortly thereafter.  No knowlingly changes to systemd or called services by user.
SELinux is preventing systemd from 'setattr' accesses on the file LoaderSystemToken-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f.

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

If you believe that systemd should be allowed setattr access on the LoaderSystemToken-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f file 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
