NAME
       booleans - Policy booleans enable runtime customization of SELinux pol-
       icy.

DESCRIPTION
       This manual page describes SELinux policy booleans.

       The SELinux policy can include conditional rules that  are  enabled  or
       disabled  based  on  the  current  values  of a set of policy booleans.
       These policy booleans allow runtime modification of the security policy
       without having to load a new policy.

       For  example,  the  boolean httpd_enable_cgi allows the httpd daemon to
       run cgi scripts if it is enabled.  If the administrator does  not  want
       to  allow  execution of cgi scripts, he can simply disable this boolean
       value.

       The policy defines a default value for each boolean,  typically  false.
       These  default  values can be overridden via local settings created via
       the setsebool(8) utility, using  -P  to  make  the  setting  persistent
       across  reboots.   The  system-config-selinux tool provides a graphical
       interface for altering the settings.  The load_policy(8)  program  will
       preserve  current  boolean settings upon a policy reload by default, or
       can optionally reset booleans to the  boot-time  defaults  via  the  -b
       option.

       Boolean  values  can  be  listed  by using the getsebool(8) utility and
       passing it the -a option.

       Boolean values can also be changed  at  runtime  via  the  setsebool(8)
       utility  or the togglesebool utility.  By default, these utilities only
       change the current boolean value and do not affect the persistent  set-
       tings, unless the -P option is used to setsebool.
