--- Comment #13 from Jan Kratochvil jan.kratochvil@redhat.com --- (In reply to Ralf Corsepius from comment #12)
This is intentional, because %dist tags in changelog entries will force maintainers to modify their specs each time they are merging from different branches.
When making a backport this is useful as one sees on which branch the change being backported has been made. Missing %dist tag is a disadantage. I have no idea what you are talking about.
Nobody with a little experience in Fedora would apply $dist tags in changelog entries and ... almost nobody has done so for > 10 years.
I have started using %dist tags in gdb.spec after 2 years of its maintenance and I find it useful during backporting for another 7 years.
I have removed that %dist it in libipt.spec to be packaging guidelines compliant, it shouldn't be heavily maintained package and after all it is not the only thing I disagree with in general.
