Description of problem:
SELinux is preventing /usr/lib/systemd/systemd from 'mounton' accesses on the directory /etc.

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

If you want to allow systemd to have mounton access on the etc directory
Then you need to change the label on /etc
Do
# semanage fcontext -a -t FILE_TYPE '/etc'
where FILE_TYPE is one of the following: 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. 
Then execute: 
restorecon -v '/etc'


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

If you believe that systemd should be allowed mounton access on the etc directory 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:
# grep (tor) /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
