The determination is usually made by yum as it is run from pilgrim on
either xs-dev.laptop.org or pilgrim.laptop.org. We sometimes attempt to
influence yum's decision by controlling what RPMs it sees.

The 'master list' is stored in the git repository I pointed you to on

I don't think I understand your question - the SRPMs contain the
"complete" sources for the RPMs they generate. You extract the contents
of RPMs with a suitable "rpm2cpio -> cpio" pipeline (nicely wrapped up
in rpmdev-extract from rpmdevtools in Fedora).

The dropbox system produces ChangeLogs which are captured in the mock
for a simple example. There is no explicit link backward from
dropbox-supplied SRPMs to development trees.

Mitch made a related comment to me a few days ago. Here's the rough idea
1. We can unpack every SRPM once into a common directory.
for some rough unpacking logic.
2. We can make a dir for each build and fill it with symlinks to the
source code that went into it. We'll probably need to parse the
build-logs for that. Code welcome.
3. We can stick a navigation overlay on top of it. See
http://dev.laptop.org/~daf/sources/sources.py for the sketch of the
idea. (Alternately, we can give out accounts on the hosting machine
and rely on grep.)
Would this help?
