Is it always the case that subsequent RPM updates of a core release can 
be upgraded using just the latest RPM built for that release?  I seem to 
remember having a problem back in RH8 days of having installed 
foo-1.rpm, having foo-3.rpm downloaded, but needing foo-2.rpm for 
dependencies for foo-3.rpm.  I.e., if I had a fresh install, foo-1 
installed, I could not install (rpm -Uvh) foo-3 directly without 
installing foo-2.  I don't know if that's still the case, but that might 
require having all the versions and letting rpm work out the 
dependencies from what's available.  Specifically, I believe it was back 
in the Mozilla-1.2 days, unless memory doesn't serve.
