FC1 to FC2 upgrade Just Works(tm) with x86_64
Wow. I just whacked in the Fedora Core 2 x86_64 DVD, went through the upgrade steps, rebooted, and everything just worked. Could not believe it.
Despite all the hoopla around regarding 4k stacks and the nvidia binary drivers, this is not an issue on amd64. I've heard that the 64-bit kernel in FC2 still uses 9k stacks, but I've not found out for sure if that's exactly why, or if it's something else. So far alsa seems to be working (I got it running on a 2.6 kernel with FC1, so perhaps I avoided some pain here since I was already configured for it), now we'll see if I can get jackd to build without core dumping when it tries to set the sample rate.
The purpose of this post: I upgraded from Fedora Core 1 to FC2. It worked. It took less than an hour. My machine "feels" faster. I'm impressed. I hadn't seen similar reports for x86_64 machines, so I'm feeding google this one.
