I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Milestone "none" is essentially what used to be called "single user mode". The kernel is up and running, but no other services have been started. Milestone "all" is multiuser mode and corresponds to what was called "run level 3". It says that all enabled services have been started.
