Description of problem:
SELinux is preventing rpc.mountd from 'write' accesses on the sock_file rpcbind.sock.

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

If vous pensez que rpc.mountd devrait être autorisé à accéder write sur rpcbind.sock sock_file par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
Do
allow this access for now by executing:
# ausearch -c 'rpc.mountd' --raw | audit2allow -M my-rpcmountd
# semodule -X 300 -i my-rpcmountd.pp
