+ This option enables the maximum policy format version supported
+ by SELinux to be set to a particular value. This value is reported
+ to userspace via /selinux/policyvers and used at policy load time.
+ It can be adjusted downward to support legacy userland (init) that
+ does not correctly handle kernels that support newer policy versions.

+ Examples:
+ For the Fedora Core 3 or 4 Linux distributions, enable this option
+ and set the value via the next option. For Fedora Core 5 and later,
+ do not enable this option.

+ running 'checkpolicy -V'. Or look at what policy you have
+ installed under /etc/selinux/$SELINUXTYPE/policy, where
+ SELINUXTYPE is defined in your /etc/selinux/config.
