[libvirt] [sandbox][PATCH 2/2] virt-sandbox-service: mount /var after all other file systems

[Cédric Bosdonnat]

When creating a sandbox with an image file, the /var folder contains
the mounted image. If we mount it before other file systems, how
could we possibly mount them? The new /var won't contain the mounted
image.
