cd ~olpc

# (aka xo-info)
grep -v "garbage-to-ignore" /etc/issue /boot/olpc_build
ls -Ld /versions/* /versions/contents/* /versions/pristine/*  /versions/configs/*
ls -ld /versions/running /versions/boot

cd ~olpc
./log-update >>log-update.out 2>>log-update.out

Assumed that scripts are in /home/olpc , both have 'x' execute bit set.

Currently need to set manually the version number to update, future feature is passing it along, or picking from list (or latest).
