/* DRBD configuration module v1.7 */

/* heavily modificated to accept new configuration file, using
   new objects and parser.

/* by Daniel Mealha Cabrita (dancab@conectiva.com) */
/*
   v1.0 first version
   v1.1 june 8th, 2000
   v1.4 august 28th, 2000
        wrote the probe/restart routines the right way (now using linuxconf's probe)
   v1.5
   v1.6 november 29th, 2000
        changed the way the drbd entries' list refreshes: now it no longer
        flashes and the last selection is kept
