=====CentOS 7 - List SELinux contexts=====
  * First, install setools:<code>yum install setools</code>

  * List all types:<code>seinfo -t</code>
  * List all users:<code>seinfo -u</code>
  * List all roles:<code>seinfo -r</code>
  * List all booleans:<code>seinfo -r</code>
  * Help:<code>seinfo --help</code>
 
====Example====
You want to add a CIFS share and set the correct SELinux context on the shared directory and below.
  * Find the samba type:<code>seinfo -t |grep samba
   samba_secrets_t
   samba_spool_t
   samba_unconfined_script_exec_t
   samba_net_t
   samba_var_t
   samba_net_exec_t
   samba_net_tmp_t
   samba_unconfined_net_t
   samba_unconfined_script_t
   samba_unit_file_t
   sambagui_exec_t
   samba_share_t
   samba_initrc_exec_t
   sambagui_t
   samba_etc_t
   samba_log_t</code>
  * We probably need ''samba_share_t''. 
  * Check already configured contexts:<code>semanage fcontext -l</code>
  * Set the context, if you don't know how, check ''semanage fcontext %%--%%help'' and read the ''semanage-fcontext'' manpage (with examples).<code>semanage fcontext -a -t samba_share_t "/opt/smbdata(/.*)?"</code>
