      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
