That's much later than is desirable for these patches. The goal is to have the system as quiet as possible. Historically, I believe the only things running in single-user mode are init and the shell. There's more than that now, but it's still pretty limited. The reason that the system needs to be quiet is that (for instance) a patch might install new versions of two kernel modules. If one of them was currently loaded and the other was not, activity on the system might cause the new one to be loaded. If it's not compatible with the already-loaded old version, bad things might happen. > By convention, all non-system services would be (strongly) recommended > to depend upon this service.

I believe that the point you describe pretty much corresponds to milestone/multi-user. I don't have a strong opinion on whether non-system services should be encouraged to wait for such a milestone. _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
