> What are the changes of a 4.3+ version that runs a 2.6.16 kernel? I know Non-existant at best. A kernel that new will never ship with centos4. Once you have 4 installed you're welcome to rebuild your own kernel, however doing so isn't supported. If it breaks, you get to keep the pieces. -- Any sufficiently advanced technology is indistinguishable from magic. -Arthur C. Clarke
