21.1Sapb#
31.1Sapb# Makefile snippet to build a miniroot kernel module (e.g. miniroot.kmod)
41.1Sapb#
51.1Sapb# Required variables:
61.1Sapb#	NETBSDSRCDIR	top level of src tree (set by <bsd.own.mk>)
71.1Sapb#
81.1Sapb# Optional variables:
91.1Sapb#	MINIROOT	Basename of the kernel module to be created.
101.1Sapb#			".kmod" will be appended to get the file name.
111.1Sapb#			[default: miniroot]
121.1Sapb#	RAMDISK		Basename of the ramdisk to be embedded in the
131.1Sapb#			kernel module.  This is used as both a directory
141.1Sapb#			name (${.CURDIR}/../ramdisks/${RAMDISK}) and
151.1Sapb#			as a file name within the .OBJDIR of that
161.1Sapb#			directory (${RAMDISK}.fs).  [default: ramdisk]
