I think Red Hat have publically stated that what used to be the stable distribution will now be a test bed for the Enterprise distros, breaking compatibility on a regular basis. From my point of view, I don't want to be an alpha tester all the time - there's enough to keep track of in Linux audio as it is. I regard the situation as unfortunate, because I think stable, free as-in-beer distributions that can be installed and used by the average person are important. The number of distributions that meet this criteria seems to be shrinking, not growing. Red Hat and SUSE have become the new proprietary UNIX with 'enterprise' pricing, Debian and Gentoo (and to a lesser extent Slackware) retain their tech elitism - and then there's Lindows, Lycoris, Xandros, Libranet etc competing for the pay-to-play market. At least Mandrake is still interested in taking free software to the general public, and dyne:bolic has that vibe which I suspect got most of us interested in Linux audio in the first place.
