Thank you, I will have a look through this.
Are there any caveats I need to be aware off?

I am planning on taking notes of all the changes and actions I take and post 
them back to the list. (This thread is here to keep a record as well :) )

Lets start with the basic info about my installation:
Distribution: Gentoo
Cyrus version: 2.3.14-r3 (The "-r3" is, afaik, Gentoo-specific)

I don't appear to have these files:
**
diff -u /usr/lib/cyrus/cyrus-db-types.active \
           /usr/lib/cyrus/cyrus-db-types.txt
**

Are these Debian specific? Or is there something missing from my installation?
Or do these only exist when Cyrus is not running? (Which I would find strange)

And from what I gather, the instructions refer back to the contents of these 
files.
Is there a way to get these files created?

Thanks,

Joost
