=== steps to create openwrt extroot pivot overlay ===
+ prepair usb stick
in virtualbox ubunto on osx host:
plug in usb device, it mounts in osx (or click initialize if filesystem not recognized)
unmount stick in osx finder
in virtualbox taskbar: Devices > USB Devices > click your device
now mounts in ubuntu
run $sudo gparted
+ format
format usbstick with gparted in linux (sudo gparted)
partition 1: 'extroot' ext4 4096MB
partition 2: 'swap' linux-swap 2048MB
partition 3: 'data' ext4 1024MB
+ power on wifibox
+ ssh to wifibox
+ check status
$df -h
+ create folders in root
$mkdir /overlay-boot
$mkdir /data-usb
+ plug in usb stick
+ mount, tar copy files to stick, unmount
$mount /dev/sda1 /mnt ; tar -C /overlay -cvf - . | tar -C /mnt -xf - ; umount /mnt
+ find uuids
$block detect > /etc/config/fstab ; vi /etc/config/fstab
+ adjust fstab to the following:
with vi (i is insert, esc change mode, type :wq to write/save and quit)
$cat /etc/config/fstab

$mount
+ problem:
read-only instead of read-write filesystem, while rw,sync is set in options for mount: https://stackoverflow.com/questions/31029731/openwrt-extroot-as-overlay-mounted-as-readonly
overlay-boot works, data-usb is not found
