extroot

Expand the router's storage space, from few MB to several GB, by using a USB storage device.

extroot implies moving the router's overlay partition to this external USB device

• Minimal requirements: kmod-usb-storage kmod-fs-ext4 block-mount
• Extended functionalities: e2fsprogs fdisk lsblk cryptsetup kmod-crypto-ecb kmod-crypto-misc kmod-crypto-sha512 kmod-crypto-user kmod-crypto-xts kmod-loop kmod-fs-isofs

What this script should be doing:

• check minimal packages
• find usb & fetch overlay uuid
• mount uuid, clean partition, copy files from device's overlay
• check uci config, adjust accordingly
