Useless on public servers that don't run RPC. Useless on flash-based servers where minimizing writes is necessary.

As said before, the topic is always struck down and nobody from core has ever stood up to say "we'll support this". I don't know whose on core this week, nor will I at any given time. I just know that core has either struck it down or been Silent. > I find it very hard to believe > that core would suggest someone NOT implement a good framework for doing full > binary upgrades via the network. A good binary update mechanism shouldn't be just the network. Updates from flash devices, ISO images, etc should all work much the same way. > Unless you mean "core@ said they would not support packaging the base" which > is different. People have clearly identified the problems that prevent a useful binary update mechanism from working, and what they need from core.

(Case in point - freebsd-update works fine without it) freebsd-update works "fine" if you run GENERIC with no build options. Back to "useful for home computers". freebsd-update is hampered by the exact problems I'm listing here. Difficulty determining "what I have", no method to store "what I did" and no effective backout mechanism to speak of. Nobody that I know cares whether or not the solution manifests as core os packages, but some sort of core versioning ability has to be developed and supported by the core. > > popular suggestion, but not the only path.

You're arguing my own points. Again, nobody (that I know) cares that it manifests as core OS packages. Certainly the existing package system used for ports wouldn't work as-is for this task. But the have/did/undo problems remain to be solved. -- Jo Rhett senior geek SVcolo : Silicon Valley Colocation
