Description of problem:
IT WENT CRAZY ON MY DRIVE ITS WREAKING HAVOC

Help me Fedora people you are my only hope
SELinux is preventing gnome-session-b from 'watch' accesses on the directory /run/media.

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

If you want to allow gnome-session-b to have watch access on the media directory
Then you need to change the label on /run/media
Do
# semanage fcontext -a -t FILE_TYPE '/run/media'
where FILE_TYPE is one of the following: abrt_var_cache_t, accountsd_var_lib_t, auth_cache_t, auth_home_t, cache_home_t, cgroup_t, config_home_t, data_home_t, dbus_home_t, dbusd_etc_t, etc_t, faillog_t, fonts_cache_t, fonts_t, gconf_home_t, gkeyringd_gnome_home_t, gkeyringd_tmp_t, gnome_home_t, gnome_initial_setup_var_run_t, gstreamer_home_t, icc_data_home_t, lib_t, locale_t, mount_var_run_t, mozilla_plugin_tmp_t, mozilla_plugin_tmpfs_t, pam_var_run_t, systemd_logind_sessions_t, user_home_dir_t, user_tmp_t, usr_t, var_auth_t, var_lib_t, var_run_t, xdm_home_t, xdm_log_t, xdm_spool_t, xdm_tmpfs_t, xdm_var_lib_t, xdm_var_run_t, xkb_var_lib_t, xserver_log_t.
Then execute:
restorecon -v '/run/media'


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

If you believe that gnome-session-b should be allowed watch access on the media 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:
# ausearch -c 'gnome-session-b' --raw | audit2allow -M my-gnomesessionb
# semodule -X 300 -i my-gnomesessionb.pp
