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?
AFAIK klibc still doesn't support nfs v4:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=409271 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=409272
I'm not sure whether there are reasonable ways to work around klibc, trying dracut instead of initramfs-tools might be a good start as booting from nfsv4 works there (though I've no idea yet what needs to get adjusted so it works for our live boot mode). I'm definitely interested to see nfs4 working for netboot out-of-the-box on Grml too, so if there's something where we could help please let us know.
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
Hm, a symlink pxelinux.cfg pointing to {isolinux,syslinux}.cfg isn't enough, right? Any chance you could provide a working pxelinux.cfg so we could work on an according template for grml-live (see https://github.com/grml/grml-live/tree/master/templates/boot/isolinux )
