genkernel, default preemption

[audiodef]

Is it possible to pass on the command line an argument to genkernel to automatically use the fully preemptible option instead of the default desktop preemption model? (For rt-sources.)

I see that genkernel compiles filesystem support as modules. When I manually compiled, I learned this was a no-no and to compile filesystem support into the kernel. So I've been using --menuconfig to go in and manually change ext4 to *. Can I leave it at the default of M?

It's only a no-no if you sometimes don't have an initramfs. Genkernel puts the filesystem modules in the initramfs it makes so the needed ones can be loaded before root is mounted. So, if you use genkernel to make the whole smash, you can leave it as the default.

However, if you don't like genkernel throwing away your --menuconfig selections each time, you can add

Much appreciated, thank you.
