Dear Folks,
The dhcp-hackers mailing list strips off patches!  I have not found
archives of it either, so I've put the patch on my web site:
http://nicku.org/software/isc-dhcp-next-file-patch/dhcp-3.0.5-next-file.patch
and the aggregator is at:
http://nicku.org/software/isc-dhcp-next-file-patch/dhcp-aggregator.pl
A description of how it works (written before I started work on it) is
at
http://nicku.org/software/isc-dhcp-next-file-patch/brendans-cunning-plan.txt

You might also want to see the description at http://nicku.org/software/.

I'd really like to work with you guys and ladies to get this into the
ISC dhcp server (so then I don't have to maintain it for each
release!).

I'd appreciate any feedback and ideas for improvement, especially ways
of making it simpler.  I have worked hard at shrinking the patch down till
it is now 634 lines.
