kpartx/del-part-nodes.rules

   1 # These rules can delete partitions devnodes for slave devices
   2 # for certain aggregate devices such as multipath.
   3 # This is desirable to avoid confusion and keep the number
   4 # of device nodes and symlinks within limits.
   5 #
   6 # This is done only once on the first "add" or "change" event for
   7 # any given device.
   8 #
   9 # To suppress this, use the kernel parameter "dont_del_part_nodes",
  10 # or create an udev rule file that sets ENV{DONT_DEL_PART_NODES}="1".
