Re: Debian needs more buildds. It has offers. They aren't being accepted.

If it happens for all archs sure. But I would hate anyone who uploads
a new mozilla or galeon because one unstable version of gcc on say
alpha has an RC bug preventing it from getting build. Or because a
-dev file of another package was miscompiled and gets a recompile
binary NMU.

Adding a conflict for a version that will be gone forever in a month
and forcing the 10 other arch to rebuild for it is a lot of buildd
time wasted.

So lets clear this up so I don't do something wrong if I ever becaome
DD and take over the buildd admin job. Last time I saw this hapening
here I asked on #debian-devel because I wasn't sure and got told (by
some maintainers, not buildd admins) that such arch special temporary
problems should not be added to the Build-Depends/Conflicts. Was that
wrong? Or would a patch be added to source-dependencies-unstable for
the duration of the build for that?

The waiting for a bug would be to get packages rebuild, which is what
was the problem in the mail. You only get the "Should I build?" mail
on the next upload. If the bug is against another package there is no
reason for another upload, so you won't get the mail.

The obvious example would be

Build-Depends: libc7-dev (>>1.2.3)

where of cause libc6-dev was ment. Or when a library was obsoleted and
removed/replaced. I ment of course not yet ready but existing
Build-Depends and not typos.
