1#	$NetBSD: Makefile.makedev,v 1.15 2008/10/25 22:27:34 apb Exp $
2#
3# Makefile snippet to add ${MAKEDEVTARGETS} devices to the mtree list
4# (if set), otherwise copy .OBJDIR-of-etc/MAKEDEV to ./dev
5#
6# If this is to be used with Makefile.image, then this file should be
7# .include-d first.
8#
9# Required variables:
10#	NETBSDSRCDIR	top level of src tree (set by <bsd.own.mk>)
11#	MACHINE		machine name (set externally by build framework)
12#
13# Optional variables:
14#	MAKEDEVTARGETS	targets to create with .OBJDIR-of-etc/MAKEDEV
15#
16# Variables modified by this:
17#	MAKEDEVSCRIPT	path to .OBJDIR-of-etc/MAKEDEV
18#	MTREECONF	may get "devices.spec" added
19#	LISTS		may get "list.makedev" added
20#	IMAGEDEPENDS	may get ${MAKEDEVSCRIPT} added
21#	PARSELISTENV	may get MAKEDEVSCRIPT=... added
