As discussed earlier bzip2 is *much* slower that gzip and really hurts on slower arches and systems, so I'd suggest that - especially for binary packages - gzip should remain the default for all normal cases and bzip2 should reserved for cases where there is a really significant size decrease. > source-only uploads > ------------------- > The current "winning" opinion is to go with the source+throw away > binaries route.

Main use case I have is kernel udebs where it is sometimes necessary to upload udebs to unstable built from a kernel version in testing. Our own build methods support that, but it would get undone by a rebuild. Our build method also ensure that all uploads are based on the same kernel version, something that's much harder to ensure when it's left to the buildds. > The extra source case > --------------------- > This issue is the one traditionally known as the linux-modules-extra > problem but also exists for some compiler packages and in the past > existed for things such as apache2-mpm-itk and so is a more general > problem.

Nice. Cheers, FJP
