What about calling
dh_installtex
without any argument. It works well, although it adds a lot of useless
stuff to the postinst/postrm script. I used it in the pgf or prosper
package to generated the correct invocation.

Ok, this would be nice. And it could be implemented in the general case,
no? If we do it in the right order maybe also the calls to mktexlsr in
the other packages (with maps etc) only updated the right trees.

Ok.

Hmm, but this is not completely trivial, I will check the debhelper
documentation how to do this.

I didn't check, but the difference is that in the postrm case errors
should be caught because maybe mktxlsr is not present, will in thre
postinst case it should be present in any case!
