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.
