All sorts of stuff. Check the yum source code. For starters the other things
mentioned already:, epochs, and the fact that all packages are considered to
be providing all files they contain, even with dependencies. But consider
this too: RPM's notion of version comparison is a bit unintuitive when it
comes to mixing letters and numbers -- is 1.2b3 greater or less than 1.20?
What about 1.2.0? And for that matter, is 1.9 higher than 1.10?
