I have never really used this however after a short walk thru it it actually looks to be a fairly useful…

It still never ceases to amaze me at the how easy it is to upgrade between versions on linux (debian for me) whilst there are obviously alot of complexity for super custom machines but still, the ability to be able to edit a single config file (sources.list) and run 3 commands and then your done is nothing short of awesome. Also to do this all whilst on SSH well nioce..

edit sources.list

# apt-get update
# apt-get install apt dpkg aptitude
# apt-get dist-upgrade

answer a few questions then..

reboot
