SELinux/Policy store

A policy store contains the SELinux policy package and system administrator modifications combined in a single, logical entity. Multiple stores can be used on a system, allowing administrators to have separate SELinux policies which can be switched (either directly or after reboot).

Policy store location
The policy store is located in in a subdirectory called after the policy store.

Pre-defined policy stores are strict, targeted, mcs and mls, but this can be fully configured by the administrator.

Policy differentiation
By allowing multiple policy stores, administrators can support different policies on a single system.

For instance, an administrator might have both strict and mcs available. The strict policy does not support MLS, whereas mcs does (but with a single security level).
