I'll tell you the same thing I told Kostik way back when I removed it. 
This is the only thing that anyone has ever suggested a use for in 
/etc/rc.early, and the "solution" in the man page is a hack. :)

If this is something that is necessary to do then I'd prefer to do it 
properly and add an /etc/rc.d/gmirror that runs in the proper (early) 
position, and then figure out the proper location in rc.d to handle the 
second half of the configuration.

I'm happy to review patches.  :)
