+Subject: [PATCH] bwrap: Fix selftest to be truly immutable
+
+We should never have any effect on the host system, so let's
+use the more direct APIs which allow us to use the immutable
+flag, don't mount `/var` etc.
+
+Crucially this also avoids us running through the tempetc
+guard which would try to rename `usr/etc` which can trigger
+on an ostree based host.
+
+Closes: https://github.com/coreos/rpm-ostree/issues/2771
