Description Rafal 2020-12-19 09:02:35 UTC 
Description of problem:
SELinux is preventing systemd-user-ru from 'unlink' accesses on the lnk_file user.

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

Aby systemd-user-ru powinno mieć domyślnie unlink dostęp do user lnk_file.
Then proszę to zgłosić jako błąd.
Można utworzyć lokalny moduł polityki, aby umożliwić ten dostęp.
Do
można tymczasowo zezwolić na ten dostęp wykonując polecenia:
# ausearch -c 'systemd-user-ru' --raw | audit2allow -M my-systemduserru
# semodule -X 300 -i my-systemduserru.pp
