When kernel-0.96 came public, i checked it out on my Amiga as it was released for Motorola chips as m68k … and still is :)
Then RedHat came with their first distro, so i had it running on a Motorola 68060 for some time. It was the swap from i386 to i686 and later, with Vesa local bus, my Amiga lost the performance race. Then, a good friend gifted me an i686 PC. WindowsXP was on it and boah, what a crazy shit that was. Filenames and libraries had stupid names and in a file hirarchy, everything was just dumb there, so installed RedHat on that and since then it was all good.
Fedora came, RedHat closed their enterprise buisness sector and then we had Fedora. Up until doday im using it and enjoy the community, wich has a very scientific and innovative spirit. Fedora was always one of those distros, going new ways on a stable and solid base, thanks to RedHat.
Even if RedHat would drop out completely with their Fedora support - wich will never happen - Fedora would be mature enuff to survive. Should Fedora nontheless go for another path wich im not happy with, ill change, but it does not look like that
So nope, im not worried a single bit^^
