I've never run into a :system that had a real use for more than three run levels - powered :off, maintenance, and up - though I've not dealt with Some of the machines I work on have three useful multi-user states. Runlevel 2 is plain-old multi-user mode, where filesystems are mounted, and the normal collection of services (mail, telnetd, ftpd, etc) are running. Run level 3 adds the DBMS, run level 4 adds the database dependent application. :P.S. - anyone else remember rc.single? Anyone care? Haven't seen one since Ultirx. shudder.
