But, as you may have noticed, a rather small percent of people choose to limit themselves to an 'open source world'. What that means for the rest of us is that we will have to keep supporting Microsoft for the rest of our lives - and putting up with their problems. > Red Hat Enterprise Linux does > maintain it, and this limits what features can be added and is extremely > challenging. Whatever happened to the idea of doing disruptive changes in odd minor number kernels? From a user's perspective, a driver change is disruptive once you get to the point where one works correctly. Is Xen going to make this better or worse? I've always wanted to install a base OS once per piece of hardware and never change it unless I add new hardware capabilities. But all the packaged distributions make me install new kernels if I want a current firefox even if I have no use for the new kernel capabilities or (as has been the case with fedora a few times) the new kernel won't work with my running hardware. -- Les Mikesell lesmikesell@xxxxxxxxx
