But this means for us that we MUST change our calculating and reporting software 
too which automatically produce lots of latex-files with \input{$HOME/...}.

Then we have 2 different versions of this software, one with $HOME and one 
without.

It is often the case that we need to re-run an old calculation, then we would
have to return to an older tetex version as well!

Yes, it is very important that we use the same software-version  to recalculate
as was used for the initial certification for one machine.

It would be better to have the latex relevant parts in our software UNCHANGED.
