"Claim?" Why would somebody lie about this? I suspect that the 20 or 30 times I've "made world" are far fewer than Rod can boast but my attempts (most on running systems) have resulted in remarkably few problems (since 2.0-RELEASE, at least). My mileage: it is unwise to expect to be able to do this if one hasn't done it for each and every SNAP and RELEASE that has occurred since the last binary install. Missing a "round" or two leaves one vulnerable to the kinds of things that Rod is talking about. In other words, libraries, kernel code, header files, et.al. seem to have been closely compatible enough over the last year from minor-release to minor-release to let most programs creak through temporary version inconsistencies. That is not to say that occasional problems, in the guise of programs that do not run until they and their libraries' versions synchronise, will not be encountered. Each user must decide for themselves which of "disallow user services while making world" or "take a chance on a program or ten croaking but otherwise keeping the system up" works for them. Either way, make sure you have a current backup! Glen Foster <gfoster@gfoster.com> >From: "Rodney W.
