  42 # This is the table used by devlinks
  43 #
  44 # Each entry should have 2 fields; but may have 3.  Fields are separated
  45 # by single tab ('\t') characters.
  46 #
  47 # The fields are:
  48 #
  49 # devfs-spec: a keyword-value set of devfs specifications, describing the set
  50 #       of devfs node entries to be linked.
  51 #
  52 #       The keywords are:
  53 #
  54 #       type - The devinfo node type (see <sys/sunddi.h> for possible values)
  55 #
  56 #       name - the devinfo node name (the part of a /devices entry that appears
  57 #               before the '@' or ':').
  58 #
  59 #       addr - the devinfo node address part (the portion of the name between
  60 #               the '@' and the ':').
  61 #
  62 #       minor - the minor-attributes (the portion of a /devices name after the
  63 #               ':').
  64 #
  65 #       The keywords are separated from their valuse by an equals ('=') sign;
  66 #       keyword-value pairs are separated from each other by semicolons (';').
  67 #
  68 # dev name - the /dev name corresponding to the devfs node described by
  69 #       the devfs-spec field.  This specification is assume to start rooted at
  70 #       /dev; THE INITIAL /dev/ SHOULD NOT BE SPECIFIED!
  71 #       The name can contain a number of escape-sequences to include parts of
  72 #       the devfs-name in the /dev/-name.  These escape-sequences all start with
  73 #       a backslash ('\') character.  The current sequences are:
  74 #
  75 #       \D - the devfs 'name' field
  76 #
  77 #       \An - the 'n'th component of the address field (n=0 means the whole
  78 #               address field)
  79 #
  80 #       \Mn - the 'n'th component of the minor field (n=0 means the entire
  81 #               minor field).
  82 #
  83 #       \Nn - a sequential counter, starting at n (a *single* digit, giving
  84 #               a starting range of 0 through 9).
  85 #
  86 # extra dev link - a few devices need a second link; that is, a second link
  87 #       pointing to the first link.  This optional field specifies the /dev
  88 #       format of this second link.  This entry can also use the above-described
  89 #       escape-sequences.
  90 #
  91 # Fields can be blank; seperated by single tab characters,
  92 # Spaces are significant, and are considered part of a field. IN GENERAL THIS
  93 # MEANS THERE SHOULD BE NO SPACE CHARACTERS IN THIS FILE!
  94 # All fields must be present (even if blank)
  95 #
