That sound good, I was thinking to include more information. Trouble is
that my script scans only binary packages at this time and the machine
I'm doing this on is alreay at 95% of it's disk capacity, so there's not
really much room for including source packages.
That is, unless there is a mechanism that I could use to automatically
track new packages that enter the archive. That would take away the need
for a complete mirror and I could just delete the processed packages.
Any ideas how to do that? The buildds must be doing something similar..

That would be nice indeed. Some of the bugs I've come across could have
been found easily with an automated vulnerability scanner. Especially
stuff like passing user-controllable format strings to syslog() just
shouldn't happen any more..
The script could also scan packages for other interesting facts like
"includes header file sys/socket.h"
"installs into /etc/cron*"
"installs into /usr/lib/cgi-bin"
..
Anyone with big enough a machine to have this run on? :)
I'd volunteer to write the extraction scripts.
Cheers,
Max
