[RFC] Switching dpkg-deb --uniform-compression by default

[Guillem Jover <guillem@debian.org>]

Hi!

I'd like consider switching dpkg-deb --uniform-compression by default,
so that both control.tar and data.tar members use the same compression,
which currently would be xz (or gzip with -Zgzip).

This would give us more uniform and smaller packages. I think the d-i
people wanted something like this (?).

Not all .deb parsers support control.tar.xz yet, but most do:
<https://wiki.debian.org/Teams/Dpkg/DebSupport>

Any package using bzip2 as compressor would need to be fixed, as
--uniform-compression only supports xz and gzip. See the MBF at
<https://lists.debian.org/debian-devel/2016/07/msg00113.html>.

dak and lintian would need to accept those, and then dpkg be switched.

Would there be any objections to this?

Thanks,
Guillem
