Description Thomas Neuber 2023-06-16 04:26:43 UTC
Description of problem:
SELinux is preventing nfsidmap from 'write' accesses on the sock_file io.systemd.DynamicUser.

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

Wenn Sie denken, dass es nfsidmap standardmäßig erlaubt sein sollte, write Zugriff auf io.systemd.DynamicUser sock_file zu erhalten.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen:
# ausearch -c 'nfsidmap' --raw | audit2allow -M my-nfsidmap
# semodule -X 300 -i my-nfsidmap.pp
