# This file executes the commands in the rcS.d directory, which are necessary

#
# 	establish minimal network plumbing (for diskless and dataless)
#	mount /usr (if a separate file system)
#	set the system name
#	check the root (/) and /usr file systems
#	check and mount /var and /var/adm (if a separate file system)
#	mount pseudo file systems (/dev/fd)
#	if this is a reconfiguration boot, [re]build the device entries
#	check and mount other file systems to be mounted in single user mode
