Also:

1) The submitter's email client corrupted the patch making it unusable anyways,
   it munged tabs into spaces etc.

2) At this point in time ->nodename is going to be something like "(none)" and
   therefore not very useful.  This only gets set after userland has started
   up.

So really, the nodename would need to be specified as well as a command line
option for this to really be useful.
