I have used Red Hat 6.0, 7.2 and very recently migrated to 9.0. I use very few features offered by RH. Normally I don’t even notice the different kernel or some libraries running on my system. Open source things get better with each version. So be happy with yourself for having a next version of every software. But there are few things which I just could not ignore. * Installation is a breeze! The graphical installation not only makes the procedure easier but also much more pleasant.
