This is what I guessed. However, it revials the following questions:
- Is it necessary to *untar* the tarball in the postinst or not?
(I guess not - why not just shiping the plain files inside the
package)
- Where should this *temporary directory* should be placed.
Currently it is in /usr/lib/fis-gtm which is terribly wrong
for temporary directories. I'd say something like /var/tmp/fis-gtm
or something like this (I need to check whether debian packages
should contain files in /var/tmp or whether /var/lib should be
prefered)
- What files *really* need to be in this directory (see my other
MoM mail)? My guess is that *.o files are not needed at all.

I will just trust you here as the expert, but it would be interesting to
know what *exactly* needs to run on the target machine. I guess
untaring a tarball is not necessarily a part of this machine dependant
installation process. So the question is: Which part really needs to
be on the machine and which one not.
Please also consider the following problem: The fis-gtm-initial package
serves only one single purpose to bootstrap a "real" fis-gtm package (at
least this is what I have unerstood). So I wonder whether the initial
package which finally bootstraps the real thing could perfectly run on
any machine and rather the installation of the final package which is
intended to run in production needs to undergo the "install on very same
machine" procedure.
In other words: As far as I understood the issue in Debian we need a
package we can Build-Depend from to build the fis-gtm package targeting
at production machines. This Build-Dependency will run on any random
machine which is just running in a freshly created chroot of the build
machine. Do such special cases require the "should be run on the
machine where a binary GT.M distribution is being installed" feature?
It actually serves the single and only purpose to build the production
package and will be deinstalled later.

You can safely assume that I know that GT.M is cool and I do not want to
blame GT.M for beeing complicated but rather complex for whatever
reasons we do not need to discuss here. I just wanted to express to Luis
that packaging GT.M is very different to the vast majority of all Debian
packages (no matter what the reasons for this different are - we need
to cope with it anyway).
Kind regards
Andreas.
