[Grml] network boot with nfs4 root

Hello,

I tried to setup a boot server with pxe. I followed loosely the wiki http://wiki.grml.org/doku.php?id=terminalserver for that. So far all went fine, except mounting the root over nfs4.

My nfs server is version4 only, and from packet logs I see that grml tries nfs version3 only over and over.

Is this a bugs or is there some trick for get it to work with nfs4?

Also, as I am using the grml96 iso image via a loopback mount, I would greatly appreciate if I could use the bootmenu for isolinux also for pxelinux. To me it seems it is mainly a matter of pathnames (and maybe symlinks) to get it to work with a statement like

LABEL grml-from-iso CONFIG <iso-root>/boot/isolinux/<common.cfg> APPEND <<iso-root>

from pxelinux.cfg

Bye,

Joerg
