#
# Makefile snippet to add ${MAKEDEVTARGETS} devices to the mtree list
# (if set), otherwise copy .OJBDIR-of-etc/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 .OBJDIR-of-etc/MAKEDEV
#
# Variables modified by this:
#	MAKEDEVSCRIPT	path to .OBJDIR-of-etc/MAKEDEV
#	MTREECONF	may get "devices.spec" added
#	LISTS		may get "list.makedev" added
#	IMAGEDEPENDS	may get ${MAKEDEVSCRIPT} added
#	PARSELISTENV	may get MAKEDEVSCRIPT=... added
