I am with Ian on this one, we have far too much code sitting out of tree and rotting faster than anyone can maintain said code out of tree, meaning we are litterly cutting our own developement efforts off, not at just the foot but up closer to the hip. The veriexec code landed, its in tree, fix it, polish it, cut out the ugly bits, but for sake of sanity do not whole sale revert it so it can generally rot some more. Officially this code is on the 12.0 target path, it needs to be in the tree sooner where many eyes can work on it. -- Rod Grimes rgrimes@freebsd.org
