From 266e1c10ec8c2734a902ac1a9ab7a20b130fcb03 Mon Sep 17 00:00:00 2001
From: Daniel J Walsh <dwalsh@redhat.com>
Date: Thu, 19 Oct 2017 17:30:50 +0000
Subject: [PATCH] Change buildtags based on installed environment.

Determine if selinux is available before building cri-o with support.
Don't add ostree support to crio or any tools other then kpod.
cri-o does not use ostree.
