Description of problem:
SELinux is preventing systemctl from 'create' accesses on the lnk_file var-lib-snapd-snap-core-3440.mount.

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

If you believe that systemctl should be allowed create access on the var-lib-snapd-snap-core-3440.mount lnk_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 'systemctl' --raw | audit2allow -M my-systemctl
# semodule -X 300 -i my-systemctl.pp
