When the source tree is dirty and contains untracked files, package builds may fail, for example, when a broken symlink exists, a file path contains whitespaces, etc. Since commit05e96e96a3("kbuild: use git-archive for source package creation"), the source tarball only contains committed files because it is created by 'git archive'. scripts/package/gen-diff-patch tries to address the diff from HEAD, but including untracked files by the hand-crafted script introduces more complexity. I wrote a patch [1] to make it work in most cases, but still wonder if this is what we should aim for. To simplify the code, this patch just gives up untracked files. Going forward, it is your responsibility to do 'git add' for what you want in the source package. The script shows a warning just in case you forgot to do so. It should be checked only when building source packages.

%description headers
|
|
Kernel-headers includes the C header files that specify the interface
|
|
between the Linux kernel and userspace libraries and programs. The
|
|
header files define structures and constants that are needed for
|
|
building most standard programs and are also needed for rebuilding the
|
|
glibc package.
