Ok, I did it that way as you suggested. The dh_installtex now inserts
simply
	update-texmf-config language
or 
	update-texmf-config updmap
into the postinst script. That in turn (installed into /usr/sbin) simply
calls
	dpkg-trigger texmf-language
or
	dpkg-trigger texmf-updmap
and not does anything else. The point here is that the postinst/trigger
action of tex-common will call update-* anyway.

That way calls from root to update-* work as before, and only the
maintainer scripts will call the update-texmf-config script.

Now if I only could test that out ...

Best wishes
