Luke Macken, Will Woods, and I were talking about something just a
little less ambitious at FudCON.  Just keeping a history of config
files.  Here's a bit of a hack that could get you started.  The one
glaring problem that I see with it is that it doesn't keep a copy of the
original file.  ie: When I want to see the change, I probably want a
diff3 between the original file, my modified file, and the file rpm is
going to install.  Without the original, I can only see the changes
between my modified file and the new one.

REPO="/var/lib/rpmcraziness"
VCSCOMMIT="/usr/bin/bzr commit"
package=sys.argv[1]

changedFiles=os.popen("rpm -V %s" % package)
for fileLine in changedFiles:
    fileParts=fileLine.split()
    filename=fileParts[-1]
    if is_text_file(filename):
        shutil.copy2(filename, os.path.join(REPO, filename[1:])
os.system("%s %s" % (VCSCOMMIT, REPO))

You'll have to write is_text_file() yourself as my imagination ends
there :-)
