I'm not a aware of a good way to turn a postinst generated configuration

(or a list of known hashes) of the postinst generated configuration file
and remove /etc/GNUstep/gdomap_probes in *preinst* if it has not been
modified by the user.

# md5sum /etc/GNUstep/gdomap_probes
0350e9dc3fb96577e6cc2d8873f2fde5  /etc/GNUstep/gdomap_probes

But mine is different (bookworm, i386) and I haven't modified it:

$ md5sum /etc/GNUstep/gdomap_probes
d9d712469c9cec8898136e52142a19d1  /etc/GNUstep/gdomap_probe

Since the old postinst runs "hostname -i" (bad idea, I know) I guess
the file is going to be different across various systems, depending
on the configuration.

Ok, thanks for the additional info. So this rules out

Does that make sense?

What you could do then, is to generate the list of known hashes on-the-fly by taking "hostname -i" into account. Instead of hard-coding the hashsums, you generate them in preinst in exactly the same way as previous versions did.
