+Subject: [PATCH] compose: Ensure we've cleaned up references to tmpfs workdir
+ before umount
+
+Otherwise the `umount()` will always fail.  This hasn't been a problem
+so far while running in a external container (docker/systemd-nspawn),
+but is when running in `mock` because it doesn't set its namespace to
+be private.
+
+This should help Fedora's Bodhi, which uses rpm-ostree inside mock.
