I would prefer to solve this problem using a fixit floppy or cdrom 
anyways.  I don't think that creates a house of cards.  My systems work 
just fine.

But I've often wondered how frequently a production system has such 
problems.  I've been a sysadmin for many years and can't remember this 
ever happening.  It's much more common to blow a hard drive, or have 
flaky memory, etc.
