ostree 2012.8

[Colin Walters <walters verbum org>]

So the git log for this release isn't super exciting...the whole thing
has broadly been fulfilling my primary goal of basic continuous
integration for GNOME, and I'm happy with that.  Actually, really happy.
It's so awesome to have binaries built in some cases within 30 seconds
of a commit landing.

I'm still chipping away on the side at aspects of how to handle /etc
in the background.  More on that later.

But let me detail the interesting bit of this release, which is that we
now support building with embedded dependencies (namely, glib and
libsoup).  Because one of the primary use cases for ostree is to install
a "stable" distribution and use it to bootstrap a download of a bleeding
edge one, we should be able to build and run on quite old systems.
One approach to this is to restrict oneself only to available API on
these old operating systems, but in the end I need a bleeding edge
libsoup (because it has the sane G*Stream based API), and so I might as
well embed bleeding edge glib too.

In particular, I am highly motivated for various reasons to have the
basic ostree/ostree-pull commands work on RHEL6.  One is that the
current ostree.gnome.org build server runs RHEL6, and the second is
that I use it as a workstation on some of my machines (or at least,
I try to).

Now, how this works is quite simple, see the details here:
http://git.gnome.org/browse/ostree/tree/embedded-dependencies/README

Concretely, one can take
http://fedorapeople.org/~walters/ostree/ostree-2012.8-1.fc17.src.rpm and
build it on RHEL6.

Slightly more interesting to some people, I've made an initial Debian package:
http://people.gnome.org/~walters/ostree/debian/
It builds and runs on Ubuntu 12.04, at least as much as doing downloads.

In infrastructure land, I've been trying to speed things up by making more of
the ostree operations asynchronous.  Sadly this pretty much required fixing
GLib first (https://bugzilla.gnome.org/show_bug.cgi?id=678576 and others 
for the curious).

So where do you get it?  From git of course:

http://git.gnome.org/browse/ostree/tag/?id=v2012.8

If you want the embedded dependency tarball for 2012.8, I'd just download it
from:
