Welp, today is the day. I'm waiting patiently for getfedora.org to update their downloads pages. Although I've not seen any announcements yet, I'm hopeful it'll happen. I've been running the beta of F26 for a few days now and it's rather stable minus a couple of issues.
The first issue is a 'System Failure' in the kernel when the desktop loads. Not sure exactly what it affects. Everything seems to be working fine, but it's an error none the less. See the image below.
Next is a strange source code compiling type of error. Any source code I've had to ./configure cannot find most of the libraries/headers it needs to compile. The main one I've had trouble with is SDL as well as a few others I don't quite recall right off the top of my head. I've tried manually passing the path along with no avail. Strangely though, source that uses cmake to configure finds all libraries/headers just fine. This has made packaging RPMs of a few emulators a bust at this point.
These two issues aside I've had nothing but a great experience with Fedora 26 beta. I can't wait for the release.
