commit a7334eb0de98af11ec38b6263536fa01bc2a606c
libsemanage: validate and compile file contexts before installing
validates the fcontexts when they are still in /var/lib/selinux. Without
setfiles_t having access to read the files, validation fails and the
policy cannot be updated.
With the new userspace, the only files in /var/lib/selinux are selinux
store related files, so label it and everything inside it as
semanage_store_t. semanage_var_lib_t is completely removed and now
aliases semanage_store_t for backwards compatibility. This differs from
the v2 patch in that it adds back the ability to manage
selinux_config_t, which is necessary to manage the old module store for
things like migrating from the old to new store and backwards
compatability.

AVC shows a denial for the semodule command, running as semanage_t,
