Yep.

That's fine.
But AFAIK your FAI server cannot export a nfsroot via NFS which was
mounted by NFS from another server. So maybe you must copy those
nfsroots to your server and then export them via NFS.

Attached is a pxelinux.cfg config file (maybe you want to name it
default) which let you choose between different boot options. IT
should be easy to extend it to support different nfsroots.
