Upgrade procedure: etch -> lenny

[Chris Jones <cjns1989@gmail.com>]

I plan to upgrade to lenny over the weekend:

1. duplicate current etch system on a new partition
2. apt-get update
2. replace "etch" by "lenny" in /etc/sources.list
3. apt-get dist-upgrade

Am I missing anything?

Note: I do not want apt to mess with my linux kernel.

Thanks,

CJ
