But you do have to uniquely identify the binary that needs to be patched. So, my question is when you generate 10x the same binary, will all these 10 binaries have the same MD5 checksum? In other words: if people did a local buildworld once on a -release sourcetree will all the executables have the same MD5 as the ones on the -release cdrom? > "make world".

The question is if the project can find someone to do it ;) -- Wilko Bulte Powered by FreeBSD http://www.freebsd.org http://www.tcja.nl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
