2#
3# Makefile snippet to build a miniroot kernel module (e.g. miniroot.kmod)
4#
5# Required variables:
6#	NETBSDSRCDIR	top level of src tree (set by <bsd.own.mk>)
7#
8# Optional variables:
9#	MINIROOT	Basename of the kernel module to be created.
10#			".kmod" will be appended to get the file name.
11#			[default: miniroot]
12#	RAMDISK		Basename of the ramdisk to be embedded in the
13#			kernel module.  This is used as both a directory
14#			name (${.CURDIR}/../ramdisks/${RAMDISK}) and
15#			as a file name within the .OBJDIR of that
16#			directory (${RAMDISK}.fs).  [default: ramdisk]
