From 85300a9a9dfb364ab1a5f94e6d3f9e558a193be1 Mon Sep 17 00:00:00 2001 From: Sjoerd Simons Date: Mon, 13 Apr 2015 22:54:19 +0200 Subject: sandbox: only do sandboxfs for hostfs interface Only do sandbox filesystem access when using the hostfs device interface, rather then falling back to it in all cases. This prevents confusion situations due to the fallback being taken rather then an unsupported error being raised.
