I'd want to see performance figures before I accepted that doing that is actually beneficial. By doing that, you lose Red Hat's support of your kernel, you don't get its security updates, you don't any extra features Red Hat adds and you don't get the benefits of Red Hat's QA.[1] Using kernels from kernel.org is a bit like using Fedora, there are times it's appropriate, but not if you want the system to come up first time, every time, and to stay up all the time, every time. [1] It's true that in using a RHEL clone, those benefits are diluted somewhat, but the source code our vendors get from RH is what RH used to build its packages. We still benefit from RH's work. -- Cheers John -- spambait [log in to unmask] [log in to unmask] -- Advice http://webfoot.com/advice/email.top.php http://www.catb.org/~esr/faqs/smart-questions.html http://support.microsoft.com/kb/555375 Please do not reply off-list
