Quick question (applies to drgn, not libkdumpfile) - if the tarball contains some m4 rules copied verbatim from autotools, do I have to list them in d/copyright?
The answer is tricky: Per Debian Policy you have to include every license that appears. You do not have to include the Copyright statements because the files are not a compiled part of the binary.Legally, it is okay to leave the licenses out of d/copyright and I have never seen ftpmaster reject a package because the FSF All Permissive License was missing. I do not think there is an official exception for it but there is certainly an unwritten exception.
So the official answer is: include them. The unofficial answer is: it is okay not to.
