I've had 2 successful upgrades from 6.4 to 6.5 with the sl6x.repo enabled. In the past, I've never done upgrades, preferring to re-install.
I'd like to know what folks are doing with respect to enabling the sl6x.repo. Is it "just enable it!, it's ready from primetime" or are you still disabling it, doing a test drive on a test machine before reenabling across all machines?
thanks
