Easier solution: copy the .config, and then run make oldconfig -- it'll prompt you for any changes made in the new kernel, and dump any invalid options... Thanks James and Qian, But doesn't this conflict with the advice given in kernel-upgrade.xml, which says: The only situation where this is appropriate is when upgrading from one Gentoo kernel revision to another. For example, the changes made between gentoo-sources-2.6.9-r1 and gentoo-sources-2.6.9-r2 will be very small, so it is usually OK to use the following method. However, it is not appropriate to use it in the example used throughout this document: upgrading from 2.6.8 to 2.6.9. Too many changes between the official releases, and the method described below does not display enough context to the user, often resulting in the user running into problems because they disabled options that they really didn't want to. As I am going from 2.6.10-gentoo-r6 to 2.6.12-gentoo-r10, which is more than just a revision change, it would seen that 'make oldconfig' is not recomended. (top posting fixed) Maybe not, but it does make it easier-- there's no reason you can't do a make oldconfig to get the basic settings that you want/need (for example, my kernel is set up for the ATI fglrx driver install and fbsplash, and I want those settings copied over), and then do a make menuconfig and go through the kernel settings manually to see what's new. For the most part, the kernel help is extremely informative, and I recommend that one do a make menuconfig every so often anyway, just to *look* at the kernel, and read the Help for any options you don't understand. For a major kernel revision jump (and often even a minor one) I usually do that, for the reasons mentioned in the docs, but having done a make oldconfig first (or copied over my config to the new kernel) at least ensures that certain basics will be set up without me having to remember the labyrinthine collection of dependencies that results in the Enable framebuffer splash setting to even appear in the config, leaving me free to focus on the new options and decide how I want to handle them.

Re: [gentoo-user] Kernel updates
P.S. See my other posts regarding trying to get USB to work for my mobile for the inspiration behind wanting to update the kernel. I think if you get to the stage of having to debug kernel code, it is always worth at least trying the latest kernel first.

Re: [gentoo-user] Kernel updates
Thanks, Thats what wasn't clear to me. I assume this is a special case in that an 'update world' won't install new kernel sources by default? I assume that the separate kernel source trees means that a new kernel can be build in parallel to an older one, and the active kernel chosen at boot time. Thanks, DigbyT P.S. is there an easy way to confirm which kernel source (gentoo/vanilla) was originally installed?
