Hi!

This series fixes some packaging issues and brings it closer to
current standards.

Thanks,
Guillem

Guillem Jover (7):
  builddeb: Pass -n to gzip for reproducible packages
  builddeb: Move upstream repository URL into the upstream metadata file
  builddeb: Switch to a machine readable copyright file
  builddeb: Add support for all required debian/rules targets
  builddeb: Enable rootless builds
  builddeb: Map rc versions to use an earlier than version scheme
  builddeb: Try to get the user full name from the GECOS field

We should not be encoding the timestamp, otherwise we end up generating
unreproducible files that cascade into unreproducible packages.

This file is structured in machine readable form (YAML), so makes it
easier to process by other tools. Switch from a git to https URL.

within a system for compatibility or compliance checks, for example.

These have been required by the Debian policy for a while, even though
the tooling can detect and workaround their omission, but are a hard
requirement when using rootless builds.

This makes it possible to build the Debian packages without requiring
(pseudo-)root privileges, when the build drivers support this mode
of operation.

The GECOS field might contain the full name for the username, try to
use that and fallback to using the username if that is empty.

Not all kernel developers are familiar with the
background info.
I think the commit description can describe a little more about
the rationale.


For example,

This was accepted as DEP-5
(https://dep-team.pages.debian.net/deps/dep5/)

and the debian kernel package switched to
the machine-readable debian/copyright by [1].

This specifies GPL-2 for 'Files: *'.

This is wrong because not all files in the kernel are GPL-2.



The debian-kernel maintains the large list of
exceptional files:

https://salsa.debian.org/kernel-team/linux/-/blob/debian/5.8.7-1/debian/copyright

But, I doubt it is maintainable.


I wonder if it is a good thing to convert it
to machine-interpretable, but apparently wrong information.


I am reluctant to maintain the huge debian/copyright...


Ben,
Do you have any idea how to handle this?

I am not tracking the latest development in the Debian project.

Could you give me a little more context about
what you call "current standards" ?

(It is defined in Debian Policy, or accepted as DEP-*, etc.)

For example, as for "3/7: machine-readable debian/copyright",
it is DEP-5, and can be mentioned in the commit log
for clarification.

What is the rationale for "2/7: debian/upstream/metadata" ?


Ben:
If possible, could you take a look at this series?

Applied to linux-kbuild. Thanks.


I added a little more explanation about why this patch is needed.

[masahiro:
The following Debian policy is particularly important for rootless builds:
"Both binary-* targets should depend on the build target, or on the
 appropriate build-arch or build-indep target, so that the package is
 built if it has not been already."
