        * If BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
            command you define it as will be run if the init script exits.
        * Made createPath be quiet (again thanks to Eric Delaunay).
+       * Updated to install.sh to make it more robust (thanks to Adam Di Carlo)
+       * NFS support added to mount by Eric Delaunay.  It costs 10k when compiled
+           in, but that is still a big win for those that use NFS.
+       * Made 'rm -f' be silent for non-existant files (thanks to Eric Delaunay).
