Thank you for your links.
My goal is :
build a small kernel for pxe client (thin client).
When booted with it, I want to push/pull an HD-image from/to nfs-share.
So, in fact it is for maintenance of a small classroom (10 pc's).
I think to use "dd" to create the HD partition images.
Someone else some other idea's ?
Why not use direct LTSP?
I want to understand all the steps in the process.
(Knowledge is power)
so I hope that somewone can explain (help me) in detail how to build a kernel for my "thin client". (initrd ? rootfs ? ? )
nfs-share is not a problem, pxe-boot neither (via syslinux)
I have some "cold feet".
