Modified initialization

The sinit(P_ADM) process replaces init(M) and the networking daemons for clients. After initialization, sinit cleans up zombie children, provides UPS support (see the upsd(P_ADM) manual page) and handles orderly shutdown; other functionality associated with init is not available. sinit helps reduce the size of the operating system, speed up the system initialization time, and provides special functionality required by embedded systems. For details about the networking services provided, see the sinit(P_ADM) manual page.
