I also played with that reserved area somewhat back in the mists of time.

I have, in the unbootable amiga yet, an amiga drive that was partitioned 
all for an earlier version of SFS (Before it went underground and 
eventually turned up commercially), and which I believe contains all of 
the ezcron and ezhome stuff Jim and I ever wrote.  Where might I find this 
bit of magic for linux?

The idea is that if we ever could recover the real srcs, we'ed publish it 
under the GPL since any chance of deriving any income is long gone.
