Building dev images

Right now I'm trying to get pilgrim to work and build good dev images on
a freshly installed Fedora Core 5 system.  There are a number of things
I need to do once I get this working.

  - First off, document it, because it's not on the wiki that I can
    find.

  - Get a list of the RPMs used to build the image

  - Script converting those RPM names to URIs of SRPMs

  - Rebuild those SRPMs (I hear there's this thing called 'mock' that
    helps with this en masse)

  - Make a stream to build using a local repository of rebuilt RPMs

  - Get a stream built of mine and of the original RPMs

Right now I'm getting things like:

install-info:  no such file or directory for /usr/share/info/sed.info.gz
error: %post(sed-4.1.5-5.fc6.i386) scriptlet failed, exit status 1

For a lot of things (sed, readline, cpio, cpp, gzip, findutils, tar...),
not sure why.  Last time I did this I got a bunch of empty directories
that should have contained images.

I figure once I get the building to actually work, I'll move on to
figuring out how to get a list of RPMs used, and then turn those into
URLs for SRPMs, and work from there.  Not sure where to start with this
though, the build.log has some stuff but it's cryptic and may be a
little challenging to parse.

Is there any documentation at all for this?  I know I'm not there yet;
but I'm primarily concerned with figuring out exactly what RPMs are used
(so I can build proper RPMs from SRPMs) and switching over to a local
repo (so I can build an image without an -O2 enabled optimization that I
believe may be problematic on the Geode and do some tests).

It'd also be interesting to me to get bootchart on this thing, possibly
in the devel images.  The chart produced is only 173K so a hack to get
it spit into a tmpfs (i.e. to avoid writing 3 extra blocks to NAND on
every boot) would be cool but that's getting into flaming optimizations.
