The attached script I wrote a few weeks back for some random reason does
it. Need to remember to throw this into the anaconda-runtime package
since it could be moderately useful for the general case.
Usage is simple enough -- 'dumphdrlist.py /path/to/hdlist' and it will
then print the NEVRA of all of the packages as well as the disc it's on
in the format
E:N-V-R.A disc
Cheers,
