After getting AVC denial, I touched /.autorelabel and rebooted. Took about 5 minutes to finish re-labeling. Then, I started to ge more AVC denials. I clicked on the denial icon and read the details. Could someone please explain the argument in the suggested "solution" : restorecon -v '#SharedObjects' What in tarnation is '#SharedObjects' The man page for semanage and for restorcon do not even make use of such notation. So, how is a user going to correctly interpret the meaning of such an opaque item as '#SharedObjects' ? The selinux troubleshoot says: (but does not explain where the #SharedObjects directory is ) If you want to allow plugin-containe to have read access on the #SharedObjects directory Then you need to change the label on #SharedObjects Do # semanage fcontext -a -t FILE_TYPE '#SharedObjects' where FILE_TYPE is one of the following: NetworkManager_etc_rw_t, NetworkManager_etc_t, abrt_etc_t, admin_home_t, aiccu_etc_t, alsa_etc_rw_t, alsa_home_t, antivirus_conf_t, antivirus_home_t, asterisk_etc_t, audio_home_t, auth_home_t, bin_t, bitlbee_conf_t, bluetooth_conf_t, boot_t, bootloader_etc_t, cache_home_t, cert_t, cgconfig_etc_t, cgrules_etc_t, chrome_sandbox_home_t, cluster_conf_t, cobbler_etc_t, condor_conf_t, config_home_t, config_usr_t, couchdb_conf_t, courier_etc_t, cpucontrol_conf_t, cupsd_etc_t, cupsd_rw_etc_t, cvs_home_t, data_home_t, dbus_home_t, dbusd_etc_t, ddclient_etc_t, device_t, devpts_t, dhcp_etc_t, dictd_etc_t, dnsmasq_etc_t, docker_config_t, docker_home_t, dosfs_t, dovecot_etc_t, etc_mail_t, etc_runtime_t, etc_t, exports_t, fetchmail_etc_t, fetchmail_home_t, file_context_t, fingerd_etc_t, firewalld_etc_rw_t, firstboot_etc_t, fonts_cache_t, fonts_t, ftpd_etc_t, gconf_etc_t, gconf_home_t, gdomap_conf_t, getty_etc_t, git_user_content_t, gkeyringd_gnome_home_t, gnome_home_t, gpg_secret_t, gpm_conf_t, gstreamer_home_t, hddtemp_etc_t, home_bin_t, home_cert_t, home_root_t, hostname_etc_t, httpd_config_t, httpd_modules_t, httpd_user_content_t, httpd_user_htaccess_t, httpd_user_ra_content_t, httpd_user_rw_content_t, httpd_user_script_exec_t, hugetlbfs_t, icc_data_home_t, iceauth_home_t, innd_etc_t, irc_conf_t, irc_home_t, irc_tmp_t, irssi_etc_t, irssi_home_t, kdump_etc_t, kismet_home_t, kmscon_conf_t, krb5_conf_t, krb5_home_t, krb5kdc_conf_t, l2tp_conf_t, lib_t, likewise_etc_t, lircd_etc_t, local_login_home_t, locale_t, lvm_etc_t, machineid_t, mail_home_rw_t, mail_home_t, man_cache_t, man_t, mandb_home_t, mcelog_etc_t, mdadm_conf_t, minidlna_conf_t, minissdpd_conf_t, mnt_t, mock_etc_t, modules_conf_t, mozilla_conf_t, mozilla_home_t, mozilla_plugin_rw_t, mozilla_plugin_tmp_t, mozilla_plugin_tmpfs_t, mpd_etc_t, mpd_home_t, mpd_user_data_t, mplayer_etc_t, mplayer_home_t, mrtg_etc_t, mscan_etc_t, munin_etc_t, mysqld_etc_t, mysqld_home_t, nagios_etc_t, named_conf_t, net_conf_t, nrpe_etc_t, nscd_var_run_t, nslcd_conf_t, ntop_etc_t, ntp_conf_t, nut_conf_t, openshift_var_lib_t, openvpn_etc_rw_t, openvpn_etc_t, openvswitch_rw_t, pads_config_t, pegasus_conf_t, pingd_etc_t, piranha_etc_rw_t, piranha_web_conf_t, polipo_cache_home_t, polipo_config_home_t, polipo_etc_t, portreserve_etc_t, postfix_etc_t, postgresql_etc_t, postgrey_etc_t, pppd_etc_t, prelude_correlator_config_t, printconf_t, proc_t, procmail_home_t, psad_etc_t, ptal_etc_t, pulseaudio_home_t, puppet_etc_t, qmail_etc_t, radiusd_etc_t, radvd_etc_t, rhnsd_conf_t, rlogind_home_t, root_t, rssh_ro_t, rssh_rw_t, rsync_etc_t, samba_etc_t, sandbox_file_t, sanlock_conf_t, screen_home_t, shell_exec_t, shorewall_etc_t, slapd_etc_t, snapperd_conf_t, snort_etc_t, soundd_etc_t, spamc_home_t, spamd_etc_t, speech-dispatcher_home_t, squid_conf_t, src_t, ssh_home_t, sssd_conf_t, sssd_public_t, stunnel_etc_t, svc_conf_t, svirt_home_t, sysctl_fs_t, sysctl_t, sysfs_t, syslog_conf_t, system_conf_t, system_db_t, systemd_home_t, systemd_logind_sessions_t, telepathy_cache_home_t, telepathy_data_home_t, telepathy_gabble_cache_home_t, telepathy_logger_cache_home_t, telepathy_logger_data_home_t, telepathy_mission_control_cache_home_t, telepathy_mission_control_data_home_t, telepathy_mission_control_home_t, telepathy_sunshine_home_t, texlive_home_t, textrel_shlib_t, tftpd_etc_t, thumb_home_t, tmp_t, tmpfs_t, tor_etc_t, tuned_etc_t, tuned_rw_etc_t, tvtime_home_t, udev_etc_t, udev_var_run_t, ulogd_etc_t, uml_ro_t, uml_rw_t, user_fonts_cache_t, user_fonts_config_t, user_fonts_t, user_home_dir_t, user_home_t, user_tmp_t, userhelper_conf_t, usr_t, var_lib_t, var_run_t, varnishd_etc_t, virt_content_t, virt_etc_t, virt_home_t, vmware_conf_t, vmware_file_t, vmware_sys_conf_t, webalizer_etc_t, wine_home_t, wireshark_home_t, xauth_home_t, xdm_etc_t, xdm_home_t, xdm_rw_etc_t, xserver_etc_t, ypserv_conf_t, zarafa_etc_t, zebra_conf_t.

But /home is a symlink to /home on another mount point. Would not selinux be "savvy" enough to follow symlinks???
