OK, it's just a naming thing. Not sure how we can handle that in
Emdebian - renaming isn't automated, at least not currently. "Gripping"
texlive-doc-base results in only three files:



743K 2009-05-08 12:16 texlive-doc-base_2007.dfsg.2-2_all.deb
 18K 2009-05-08 12:22 texlive-doc-base_2007.dfsg.2-2em1_all.deb

Hence why I'd like to understand the problem and work out how Emdebian
can have useful packages like docbook-utils without getting into
problems with tex.

Am I going to have to blacklist packages in main that don't allow
modifications without renaming? There's no easy way of identifying such
packages either.

It wouldn't be so bad if texlive-base didn't depend (not recommend)

This element still remains:

"The bug in that dependency chain is in
texlive-base which has "Depends: texlive-doc-base" - in the context of
'apt-get install docbook-utils', that is entirely unwarranted."

Shouldn't that be a Recommends?

I still want to *not* have to install texlive-doc-base on systems that
only want to use docbook-utils and have Install-Recommends turned off. I
don't see why texlive makes that impossible.
