This file contains information about how the linux should set up the booting system
# Format for each entry: <id>:<runlevels>:<action>:<process> # # id == tty to run on, or empty for /dev/console # runlevels == ignored # action == one of sysinit, respawn, askfirst, wait, and once # process == program to run
only the active parts are listed below:
# Startup the system null::sysinit:/bin/mount -t proc proc /proc null::sysinit:/bin/mount -a
# now run any rc scripts ::sysinit:/etc/init.d/rcS
# Start and monitor AVOS ttyS0::once:/usr/bin/avos_helper.sh
This is most interesting. It seems like the avos-blob-do-it-all binary is started with the output and input(?) bound to a serial port. This port is probably accessible somewhere on the PCB and could be accessed using a level converter (like used to access the serial consoles of the older Archos devices).
# Stuff to do for the 3-finger salute ::ctrlaltdel:/sbin/reboot
# Stuff to do before rebooting null::shutdown:/bin/umount -a -r -l null::shutdown:/sbin/swapoff -a
