[OpenWrt-Devel] [PATCH] imx6: apalis: fix config survival after sysupgrade -n

[Petr Štetiar]

This patch fixes `sysupgrade -n` when flashed with rootfs of the same
size as currently running, so the rootfs_data wouldn't get destroyed and
thus survive reboot. So let's fix it by always cleaning up the content
of the rootfs_data during sysupgrade.
