At this point, wouldn't it be easier to use an existing solution
like Jenkins, and maybe add a few custom hooks where needed?

I think you're probably right, but it's worth noting that the Ubuntu install asks whether to install a set of proprietary software at some point.  So the thought of a DMD package available to Ubuntu users somehow seems entirely reasonable.

Use of /etc/apt/sources.list.d turns out to be anathema to those of use
who use approx.

Having a D apt repository remains a good move. In fact isn't there one
already? It's contents could be widened to include all deb from D stuff.

(Except I haven't actually been able to make it work :-(

It is certainly a considerable proposition. However I think getting an
active Debian Maintainer to take the materials onto his/her list of
responsibilities would, in my view, be a far more productive approach.

There are git-based tools for managing Debian packaging builds which fit
well with D being a Git oriented community.

There certainly used to be, but IIRC it has fallen into disuse.

But it's still better to have packages in the official repos, because that way 
people will be able to access them immediately without having to look for 
3rd-party repos.

Just to follow up here -- a couple of days ago I pulled LDC from GitHub and 
built it.  First time I've tried LDC in a while as up until fairly recently I 
was not aware of the work on GitHub.

Very nice and friendly build process -- I like the inclusion of druntime and 
phobos as submodules.  The executables produced are nice and fast -- maybe about 
10-15% slower than GDC for the number-crunching code I tested, but much faster 
than dmd-compiled programs, and the compilation process itself is super-fast.

I'll try and follow up in about 6 weeks' time by which time I should be settled 
in new job.  If it's all all right time-wise, and if someone can mentor me in 
production of good-quality deb files, I'd be willing to reconsider the 
maintainer issue. :-)

Is any of the code public, in the sense that you could give e.g. 
me access for benchmarking purposes? We are currently using a 
presumably suboptimal optimization pass schedule, which for 
example doesn't include the auto vectorizer, but are going to 
switch to a new built-in pass manager soon (which uses the same 
pass schedule as Clang), and it would be very interesting to see 
its impact on performance-critical code.

Here you go. :-)

It's surely not the best D code ever written (it possibly inherits too much from 
C++ in design terms), but hopefully it's still useful for your purposes.
