      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
