StartupItemContext(8)					    BSD System Manager's Manual 				     StartupItemContext(8)

NAME

     StartupItemContext -- Execute a program in StartupItem context

SYNOPSIS

     StartupItemContext [program [arguments]]

DESCRIPTION

     The StartupItemContext utility launches the specified program in StartupItem bootstrap context.  Each Darwin and Mac OS X login creates a
     unique bootstrap subset context to contain login specific Mach port registrations with the bootstrap server.  All such registrations per-
     formed within the context of that subset are only visible to other processes within that context or subsequent subsets of it.  Therefore, a
     Mach port based service/daemon launched within a login context will not be visible to other such contexts.

     To override this, a root user can use the StartupItemContext utility to launch the program within the same bootstrap context as all other
     StartupItems. All subsequent Mach port bootstrap registrations perfomed by the program will be visible system-wide.

NOTES

     All bootstrap port lookups will also be resticted to the StartupItem context. The services provided on a per-login basis (clipboard, etc...)
     will not be available to the program.
