What is the difference between init 1 and init S in Solaris?
Run level 1 is considered an adminstrative mode, usually for installing packages and so forth. In this situation, you want a minimal set of processes running, no other users logged in, and local filesystems mounted. It usually requires the /etc/inittab file for the definitions of what processes to start at different run levels. Run level s is for single user mode, usually considered an administrative mode as well, but for more of a basic environment; local file systems are not mounted and the /etc/inittab file does not have to exist. Usually, single user level is for repairing systems or troubleshooting the system.
