Exactly.

The problem is tetex-extra: Some map files are in tetex-extra, not base,
and need to be split of 00updmap.cfg. Therefore I need the scheme that
I was trying to implement even to be able to install tetex-extra.

No, I think this would confuse dpkg - at least some checks whether a
conffile does already exist, and with which hash, is done before the
configure phase.

The workaround was simply to copy 10tetex.cfg into updmap.d in
*postinst*, irrespective of whether it was missing because the package
never was installed, or because the admin has deleted it.
