[SOLVED]Kernel change concerns
Howdy,
I have a very basic installation: i3, Firefox, Emacs, GIMP, Inkscape.
I have two questions:
Would compiling and installing the Libre Kernel mess my system in some way?
Is menuconfig available for such kernel?

Re: [SOLVED]Kernel change concerns
You can install a custom kernel alongside the vanilla Arch one and choose which one to boot into via your boot{loader,manager} menu.

Re: [SOLVED]Kernel change concerns
So, should I just install the kernel and configure my grub?

Re: [SOLVED]Kernel change concerns
Linux-libre won't "mess your system", of course not, and yes, menuconfig (or nconfig, xconfig, etc) will be available.
Is it simply a philosophical thing for you, or do you see some practical benefits as well?

Well, you could say it is both but, my hardware is very limited and I want to test different configurations. This is experimental hardware so I mess a lot with it.

Re: [SOLVED]Kernel change concerns
When you build a custom kernel, ensure you name it something different from the name used by the vanilla kernel -- it is one of the configuration items in the kernel. Each kernel has a directory under /lib/modules (I think that is where they are) in which all of the modules for that kernel are stored. The directory name that contains the modules is the name of the kernel.
Edit: To make life even simpler; build in the drivers you need for your system to boot. That way you can boot without needing an initrd.
A really good reference on how to do custom kernels is the Gentoo Handbook.

I was just browsing through it yesterday. Good thing it was raining, because their handbook is huuuuge :-)

Grep for "\-ARCH" in the abs (or git) build source's config, and you will find the configuration option in question.
