tasksel avoidance

[Ian McDonald <iam@st-andrews.ac.uk>]

Simple question I hope. I'm doing network preseeds, and can't see how to 
skip tasksel completely. I've tried d-i tasksel/skip boolean true, as 
for other sections, but it's having no effect.

I've read the manual, and section B4.10 states that you can install no 
tasks, but I've tried a few combinations of no, none etc without joy 
either.
