hey all
with genkernel most of the important things work(and I can use my laptop for school)..... so how to build a new kernel on top this??? or is it better to with a clean slate??
I would like to have the option when I boot normal it boot the genkernel and when I boot advanced I can have my new kernel??
hope it makes sense or am I doing it dead wrong??
(and yes i'm new to Linux and and especially to gentoo) |

g-lock_dk,
You can do that. Ideally you should always have several kernels to choose from at boot time.
Every now and again you will make a kernel that won't boot and its easier to choose another kernel from the boot menu than to find your liveCD to fix it.
Kernels and their modules are separated by the version string as defined at the top of the Makefile.
| Code: | VERSION = 4
PATCHLEVEL = 2
SUBLEVEL = 0
EXTRAVERSION = -gentoo-r1 |
so the easiest way to have multiple kernels is to install different versions.
Let genkernel do the first one, then you update but do it yourself.
Here's a 10 year old guide. Over the years the kernel structure has changed but the method remains correct. There are many more options now, so you need a bigger pot of coffee.
Pappy said it better at kernel-seeds but that assumes you are starting from a seed.
The illustrated step by step method will help you get started and ensure you get all your "must have to boot" options.
