Only kernel in a hard disk

I think its right right place to post.

Is it possible to install only kernel in a hard drive? After installing it will it be easy to add programs and software application to it, or I have to understand Linux Kernel in detail.

And what about Linux from scratch?

Hello and welcome! :)

No, it takes more than just the kernel in order to boot and run Linux.

Yes, Linux From Scratch is a very good project to help you learn about the inner workings of Linux.

Oh thanks. First I'll try Linux from scratch.:)
