131 help
132 This option enables the maximum policy format version supported
133 by SELinux to be set to a particular value. This value is reported
134 to userspace via /selinux/policyvers and used at policy load time.
135 It can be adjusted downward to support legacy userland (init) that
136 does not correctly handle kernels that support newer policy versions.
137
138 Examples:
139 For the Fedora Core 3 or 4 Linux distributions, enable this option
140 and set the value via the next option. For Fedore Core 5 and later,
141 do not enable this option.

158 If you are unsure how to answer this question, look for the
159 policy format version supported by your policy toolchain, by
160 running 'checkpolicy -V'. Or look at what policy you have
161 installed under /etc/selinux/$SELINUXTYPE/policy, where
162 SELINUXTYPE is defined in your /etc/selinux/config.
