    Hello there! quick question about patching my linux kernel, I know how to do it and all that, but i'm just wondering, when i patch it and providing everything goes well.... will it create a new vmlinuz file in /boot that i just boot from? or will it overwrite anything in there? For instance i'm booting from /boot/vmlinuz-2.6.3 so will it create a /boot/vmlinuz-2.6.4 or will it overwrite the /boot/vmlinuz file.. i have this backed up but i just want to know where to locate the new kernel. I ask this cause i usually just download the new kernel and recompile it, i've never patched before!

    Applying the 2.6.4 patch to a 2.6.3 source tree will leave your source tree the same as if you had downloaded the whole linux-2.6.4.tar.bz2 file again. It just saves you having to download all the files again, it just contains the changes that occured between versions.

    Just apply the patch, and recompile and install as you normally would.

    The patch file is essentially a "diff" file recording the changes between the two versions. The patch utility uses this file to apply the necessary changes to the various files in the kernel source. just take a look at the changelog so you know what config settings to check when compiling.
