Code review comment for lp:~alextu/lxc-android-config/lp1575564_include_rules_in_device_tarball

I tried add the paths to debian/dirs, But it gets error becasue installation process try to remove something under /system which is a loop mount with system.img.

debian/dirs:
$ cat debian/dirs
system/ubuntu/usr/share/apparmor/hardware/audio.d
system/ubuntu/usr/share/apparmor/hardware/video.d
system/ubuntu/usr/share/apparmor/hardware/graphics.d

error:
