If you are using someone's patches, you must be patching the files that they provided. If you have created your own "imposters", you cannot expect to patch them.

Doing so would still require resolving the full dependency graph, so that programs affected by a library change could all be identified. -GAWollman -- Garrett A.

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 [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Think "make all" rather than "make world". From there, it is easy enough to generate a chain of patches just like CTM does for the sources. However, is it worth the effort? I don't know.
