A major kernel upgrade is from 2.6 to 2.7 2.6.30 to 2.6.31 is a small incremental upgrade and 2.6.30.1 to 2.6.30.2 is a bug fix Common sense tells me that you will forget something important using your method much more often than oldconfig will trip over a new option (eg the pata shuffle about 2 years ago) > I do as the kernel upgrade guide says - when going between major > versions (yes, even one), copy the old .config to the new kernel dir, > then run make menuconfig, and make sure all of your critical options are > set. This is much safer, though it does take more time. Well, that guide is someone's opinion. It is not a technical fact. I write wiki pages that seem to be to be 100% spot on and the best advice ever. But some of my colleagues ignore it and do it their way. Stuff they do does not break. -- alan dot mckinnon at gmail dot com
