3# Makefile snippet to add ${MAKEDEVTARGETS} devices to the mtree list
4# (if set), otherwise copy etc.${MACHINE}/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 etc/etc.${MACHINE}/MAKEDEV
15#
16# Variables modified by this:
17#	MTREECONF	may get "devices.spec" added to it
