I've been a long-time fan of FC and am running it almost exclusively on all of my boxes. As such I was probably one of the first to download F7 on the 31st... after installing it, I've run into some problems:

1) The installer seems to be oblivious to what you've actually chosen to install if you run it in text-mode. For instance, I checked 'web development', 'eclipse', and 'xfce' - none of which were installed; instead I was greeted with the gnome desktop which I had unchecked!

2) LSI logic controllers don't seem to be supported (didn't recognize my SCSI drives), so I popped in an old ATA card. This worked, but every few seconds I get ominous error messages from ATA popping up across the console.

Other than this, it's a very shiny and nice looking system! Now if they'd just dump yum once and for all, and use apt by default instead... I'd be quite happy indeed.
