/etc/redhat-release is from 22nd of May and is says "Florence" instead of "Seawolf".
It doesn't here. Are you sure you didn't upgrade from a previous beta that had the same version?
Yes, I did an upgrade. Sounds like I should have look further but after checking MD5SUMS, installation dates and version information I goot convinced that I have the right one. Oops myself. How many other surprises of that sort I can expect?
I don't know. But I checked the one on the ISO image, the shipped version says the right thing.
As an aside, I think this is the first bug reported against redhat-release that had to do with the actual package. :)
