I want to hear if upgrading from RH 8.0 to RH 9.0 is easy and painless. RH 9.0 officially comes out today, so I know at least some of you will upgrade your 8.0 boxes to 9.0. I'm a little scared to make the upgrade till I hear from some others who have done the same. I want to know if everything that worked in 8.0 will work in 9.0. Thanks.
