Is it possible to boot Debian Wheezy from NFS v4?
Bootwing with NFS v3 works just fine. NFS v4 not.
This is in my /etc/exports:
/nfs 192.168.100.0/24(ro,sync,insecure,no_root_squash,no_subtree_check,fsid=0)
/nfs/root 192.168.100.0/24(ro,nohide,sync,insecure,no_root_squash,no_subtree_check)
/nfs/root/www contains the root of the webserver.
The commandline is:
rootfstype=nfs4 root=/dev/nfs4 nfsroot=192.168.100.1:/root/www
fails with
mount call failed - server replied: Permission denied.
Mounting from the busybox in the initrd fails:
mount -t nfs4 192.168.100.1:/nfs/root/www /root
mounting .. failed: Invalid argument
Do I need to modify the initrd?

I think you have to create a initrd with nfs4 mount utils in it. Or maybe try this: http://packages.debian.org/squeeze/dracut.
