#	$NetBSD: Makefile.minirootkmod,v 1.1.4.2 2012/11/20 02:57:41 tls Exp $
#
# Makefile snippet to build a miniroot kernel module (e.g. miniroot.kmod)
#
# Required variables:
#	NETBSDSRCDIR	top level of src tree (set by <bsd.own.mk>)
#
# Optional variables:
#	MINIROOT	Basename of the kernel module to be created.
#			".kmod" will be appended to get the file name.
#			[default: miniroot]
#	RAMDISK		Basename of the ramdisk to be embedded in the
#			kernel module.  This is used as both a directory
#			name (${.CURDIR}/../ramdisks/${RAMDISK}) and
#			as a file name within the .OBJDIR of that
#			directory (${RAMDISK}.fs).  [default: ramdisk]

# SRCMOD is a skeleton version of miniroot.kmod, without an embedded ramdisk.
# It should already have been created by "make install" in
# .../sys/modules/miniroot, and its name includes literal "miniroot",
# not variable ${MINIROOT}.
#
# DSTMOD is a copy of SRCMOD that is modified to include an embedded ramdisk.
# It will be created by rules in this Makefile.
#
# RAMDISKFS is the ramdisk image to be included inside DSTMOD.  It should
# already have been created by the Makefile in RAMDISKSRCDIR.
