It doesn't matter if it's more secure than a chroot, because that's
not what we're talking about.  This is about whether you want
random-person-off-the-internet to upload any software they like and
run it on your server, and you *do not* want to do that with either a
chroot or a Linux container [even if OpenShift got away with it].

exploit somewhere in the large kernel API bypasses SELinux.
