Hi HPA,

We have a patch we use to bind your tftp server to a postgresql database
via http (php interface). Some fixes were done since the time we already
submitted it to you.
FYI, we succesfully use a chrooted busybox environement to execute the
code (ash script), w/ support for www (busybox wget).
ComputeMode (www.computemode.org) opensource software makes use of it,
feel free to try it.

The patch may be downloaded here (patch to the debian package, version
0.40, package renamed to ease deb upgrade) :
http://www.computemode.org/dl/computemode-1.3/cmtftp-hpa/
(get the diff.gz file, or if you would like something cleaner, please
ask us...)

Thanks for your great work on tftp-hpa and pxelinux !

Regards
