#
# Makefile snippet to add ${MAKEDEVTARGETS} devices to the mtree list
# (if set), otherwise copy etc.${MACHINE}/MAKEDEV to ./dev
#
# If this is to be used with Makefile.image, then this file should be
# .include-d first.
#
# Required variables:
#	NETBSDSRCDIR	top level of src tree (set by <bsd.own.mk>)
#	MACHINE		machine name (set externally by build framework)
#
# Optional variables:
#	MAKEDEVTARGETS	targets to create with etc/etc.${MACHINE}/MAKEDEV
#
# Variables modified by this:
#	MTREECONF	may get "devices.spec" added to it
