Instead of hard-coding the hashsums, you generate them in preinst in exactly the same way as previous versions did. Does that make sense?Yes, it makes perfect sense. But I have very poor shell scripting skills and have to figure out a way to do it. I guess I should create a temporary file and compare the md5sums with the file on the system, and silently delete it if they match. Perhaps some version check would be necessary to avoid executing it every time. Also, shouldn't this code snippet be in prerm instead of preinst (and only applicable for the "upgrade" action)?
You can't retroactively add code to existing packages. Can you be more specific, why you want to add that code to the prerm of the "existing" package?
