Hi, would it be possible to provide a) patched binaries b) an installer for these binaries c) a simple tool to backup the original binaries and restore them ? Ever since binary patches became available, I've not bothered building FreeBSD any more. None of my systems have the source, nor do I want to install it anywhere. I'm also not bothering to install this in a VM - you guys have probably done this a few times. Regards Rainer
