Pocketbook syncer

some stuff for pocketbook

use pbjb to install/run sshd

koreader as file browser/reader

koreader dropbear too old calibre integration is nice, but complicated, unreliable (start calibre, start sharing, start koreader, look for calibre...)

install entware/optware

to /mnt/ext1/optware

did not use installer script. chroot setup based on russian chroot

get busybox, start chroot, get opkg etc. cannot run sw after opkg install --- hard coded library paths?

change into chroot script set up bind mounts

passwd path hardcoded to /opt/etc! ln passwd

poc for ui sync: /mnt/ext1/applications/testhase.app
