Gotcha.  Thanks for the heads up.

My todo list for this weekend includes fixing the two platform
regressions (armv4l and x86_64), and trying to fix the Fedora build
problem.  Plus there's a new uClibc++ release out I should upgrade to.

Sure.  I have a qemu git repo on my host, I build from that every once
in a while.

Yeah, I removed it on 2009.  http://landley.net/hg/aboriginal/rev/862

I'm treating qemu as a host tool, something you get from your distro or
build on your distro.  (In theory you can bulid qemu under your target,
but if you're running your target already... chicken and egg problem
there actually being useful.)

The goal of aboriginal linux is to build a system iamge.  That's an
intentional design boundary: what you _do_ with that system image
afterwards is a separate issue. (If I don't draw the line somewhere,
feature creep will recapitulate buildroot.)

Aboriginal Linux tries to be target-agnostic.  You could have a real
versatile arm aboard, or use an emulator other than qemu. The
run-emulatorsh script works with qemu, but you can replace it with
something else (a telnet to your raspberry pi, for example). In theory,
only the run-emulator.sh script would have to change, the other two
stack on top of that.  In practice, supplying HDB and HDC, and specify
extra memory (the QEMU_EXTRA stuff) in dev-environmentsh is
qemu-specific too.

Yes we provide native-build.sh, and the more/*-from-build.sh scripts,
but the control-images are a separate project (with its onw repository)
for a reason. You could make an argument about whether or not qemu
belongs in host-tools.sh, but you don't need it to build system images,
and that's where build.sh stops.

On ubuntu 10.04, "./configure && make" in qemu just works.  I expect I
had to install buckets of dependencies, but it was long enough ago I
don't remember what they were.  Probably covered by
http://landley.net/notes-2011.html#26-05-2011 though...

Either it's "mere aggregation", or a license violation.  Pick one.
