	....  If so, does this imply that booting with the old
	FLODs and creating files for the new ones will allow me to then run
	successffully with the new ones?  This would not be inconsistent with 
	my experience so far, although I'd have to see it work before I really
	believe it.

    That is consistant with the explanation our CE gave me. His claim is that on
    some very few machines (reason undetermined) the format of the disk is
    readable with the new FLODs, however, when the FEP file system is written to
    in any way (by genera when running the new Flods) the format becomes
    corrupted. The session where the write occured will continue to run fine,
    but the next boot will fail during clear machine.

OK, so I tried it.  I booted the previously flaky-FLOD machine under the
older Genera 8.0 FLODs, created copies of the newer ones, and attempted
to boot.  As I expected, this failed in the same fashion as it had
before: a Bus error during Clear Machine.  No changes to the FEP file
system were made using the newer FLODs, indicating that the newer FLODs
are faulty regardless of whether they are used to modify the file system.
