Description of problem:
SELinux is preventing (networkd) from 'mounton' accesses on the directory /etc.

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

If you want to allow (networkd) to have mounton access on the etc directory
Then sie müssen das Label auf /etc ändern
Do
# semanage fcontext -a -t FILE_TYPE '/etc'
wobei FILE_TYPE einer der folgenen Werte ist: admin_home_t, anon_inodefs_t, audit_spool_t, auditd_log_t, autofs_t, automount_tmp_t, bacula_store_t, binfmt_misc_fs_t, boot_t, capifs_t, cgroup_t, cifs_t, debugfs_t, default_t, device_t, devpts_t, dnssec_t, dosfs_t, ecryptfs_t, efivarfs_t, fusefs_t, home_root_t, hugetlbfs_t, ifconfig_var_run_t, init_var_run_t, initrc_tmp_t, iso9660_t, kdbusfs_t, mail_spool_t, mnt_t, mqueue_spool_t, named_conf_t, news_spool_t, nfs_t, nfsd_fs_t, openshift_tmp_t, openshift_var_lib_t, oracleasmfs_t, proc_t, proc_xen_t, pstore_t, public_content_rw_t, public_content_t, ramfs_t, random_seed_t, removable_t, root_t, rpc_pipefs_t, security_t, spufs_t, src_t, svirt_sandbox_file_t, sysctl_fs_t, sysctl_t, sysfs_t, sysv_t, tmp_t, tmpfs_t, unlabeled_t, usbfs_t, user_home_dir_t, user_home_t, user_tmp_t, usr_t, var_lib_nfs_t, var_lib_t, var_lock_t, var_log_t, var_run_t, var_t, virt_image_t, virt_var_lib_t, vmblock_t, vxfs_t, xend_var_lib_t, xend_var_run_t, xenfs_t, xenstored_var_lib_t. 
Führen Sie danach Folgendes aus: 
restorecon -v '/etc'


*****  Plugin catchall (17.1 confidence) suggests   **************************

If sie denken, dass es (networkd) standardmässig erlaubt sein sollte, mounton Zugriff auf etc directory 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:
# grep (networkd) /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
