### BEGIN INIT INFO

# Default-Start:     2 3 5
# Default-Stop:
# Short-Description: Kernel source configuration switch
# description:  Adapt the configuration of the standard kernel sources
#		to match the currently running kernel. This is achieved
#		by creating an include file in /var/adm. The kernel sources
#		include these files to choose between the predefined
#		configurations. (This mechanism allows to build external
#		kernel modules for the standard kernels without first having
#		to configure the kernel by hand.)
