Re: [libvirt] [libvirt-sandbox][PATCH 4/4] libvirt-sandbox-init-qemu: Check for fopen() return value

There's a problem in mount_root(): the return value of fopen() is not checked rather than used directly. Not only this interferes with pattern laid out by other areas of the code, but it's possibly dangerous too. If opening the config file fails, @fp may be dereferenced directly.
