Build a small linux system with busybox

Hello,

i'm looking for information how to build a small linux system based on glibc and busybox.
I know http://www.linuxfromscratch.org/, but it is quite complex... I want to build a much smaller system.
Has anybody some information about it or knows a good website?
I know there are serveral "build systems", for example buildroot (http://buildroot.uclibc.org/), but i really want to build it "from scratch"

Re: Build a small linux system with busybox

if lfs is too complex for you, you should think about if you really want to make your own linux.

Basically you just need a compiled kernel and a bootloader And if you want to extend your system toolchains and compilers. But that's somehow exactly what lfs is...

Re: Build a small linux system with busybox

I have looked at the following a while back. I wanted to try to build a very small system too. I never got so far though, as I didn't have the time for it.

http://tldp.org/HOWTO/From-PowerUp-To-B … HOWTO.html
http://users.cecs.anu.edu.au/~okeefe/p2 … ldMin.html

What I never really could find a precise answer to was how much is really necessary for a system to "startup".

Would it really be enough with a bootloader, kernel and /sbin/init?
(I know there would be just about no functionality in that, but theoretically?)

One thing you can say about Linux, there will be heaps of distros that already do that for you!

Check http://minimalinux.org/ttylinux/, http://www.tinycorelinux.com (both ready-made distros) and http://www.t2-project.org for a build-your-own framework.

Pocket Linux is the bomb. Excellent guide. I contemplated creating a similar project for a USB stick (which would be much more practical nowadays). Maybe one day.
