Nice! Seems to work, even on Debian stable (I was sure I'd need at least
testing, but no!).
> Sample steps to build DEB packages:
>
> - make dist
> - cp dtrace-x.y.z.tar.bz2 $D/dtrace_x.y.z.orig.tar.bz2
This...
> - cd $D
> - tar -jxpSf dtrace_x.y.z.orig.tar.bz2
... seems rather duplicative with this. See below for a patch with a
make prep-debuild target that does this for you.
> - cd dtrace-x.y.z
> - make prep-debian
> - debuild
It is a bit annoying that you have to do a prep-debian before doing a
build, because this prevents you doing a normal apt-src or any other
large-scale build command unless you already have a source deb that this
was done to. (The changelog generation is nice though!)
I would be inclined to use git-buildpackage here. See
https://honk.sigxcpu.org/projects/git-buildpackage/manual-html/gbp.import.upstream-git.html
I tried for a minimal approach using the postexport hook, but alas gbp
wants a debian/ directory before it'll even run that :( so for now this
seems to be the best we can do.
Here's a tiny patch to let you avoid the make dist in favour of a simple
'make prep-debuild'. (I didn't fold it into make prep-debian because
some package building tools, like apt-src, don't need the .orig.tar.bz2
at all.)

Subject: [PATCH] dists: add prep-debuild target
This does the creation of the .orig.tar.bz2 in the parent of
the source tree for you.

Why 4.5.1? I guess it's what debhelper writes right now. (The current
version of Debian Policy is 4.7.3. It looks to me like we're compatible
with it.)

I've always been worried that these lists would be hard to maintain.
It's a shame we can't autogenerate them, though it's hard to imagine
from what. Maybe in the future we should do like we did for the version
numbers, and have a centralized list of files from which we can generate
things like this *and* the install commands in the Build files.

This is really nifty!

I assumed you could just stuff an || true in there, but this is being
invoked by dh_auto_configure, so that option isn't available (plus, of
course, if there's an actual error other than unknown args, we don't
want to fail).
Maybe we should just not exit with exitcode 1 on unknown configure
options, only IIRC Gentoo actually wants us to. This may be the best we
can do.

Honestly this one I think we should do upstream. I always thought that
/bin/bash is universal and /usr/bin/bash less so.

I suppose without -Werror this is safe :)
