Yes I can see how that would zap the installer.

Yes this will work but the Red Hat installer doesn't read
/etc/fstab of your old system. So it's not aware of what you did. That
is why you, as a rule do not want to do what you did.
If a partition gets full root will get mail warning you and you
can take action. What I would do is get another larger hard drive or
another hard drive and move /usr or /home to the new hard drive. That
should solve the problem and the Red Hat installer will see it.
