Description Mikhail 2018-07-03 17:59:27 UTC
Description of problem:
SELinux is preventing (coredump) from 'mounton' accesses on the file /run/systemd/unit-root/proc/kcore.

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

If you believe that (coredump) should be allowed mounton access on the kcore 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 '(coredump)' --raw | audit2allow -M my-coredump
# semodule -X 300 -i my-coredump.pp
