OK, I give up. ;-)

Agreed... or if only one machine is available, we're back to periodically
booting from a safe, known, bootable CD-R with a kernel, a copy of the
checksums and all of required binaries on it (which is fine unless someone
broke into my house and replaced the CD-R ;-)).
I guess I'll stick with what I have (i.e. the RO floppy) and hope that the
script kiddie isn't thinking that far ahead (the last one that got through
onto a previous RedHat box of mine wasn't, fortunately).
