This weekend I upgraded to Debian 4.0, codenamed Etch. The process is actually easy enough that you can do most of it using drunken monkeys (trust me).

The only funnies I got were:

• xterm disappearing. Well, one really shouldn't be upgrading from X, should one?
• xfree86 disappearing. There was actually a note in the release notes to be careful about that. Just re-install xorg and you're fine.

[EDIT]

• batch no longer takes parameters.

Now I'll be looking at moving services that I was running in a SID chroot to my main system.
