I'm trying to setup a new diskless solution with ubuntu 12.04 without any success. I followed this [Diskless Ubuntu HowTo](https://help.ubuntu.com/community/DisklessUbuntuHowto)

But the initramfs seems not to be able to mount my nfs share. 

On my server side:

My /etc/exports

```

/srv/nfs4           192.168.0.0/24(fsid=0,rw,no_subtree_check)

/srv/nfs4/nfsroot   192.168.0.0/24(rw,no_root_squash,no_subtree_check,fsid=1,nohide,insecure,sync)

```

I'm able to mount my nfs share on standard Ubuntu installation without any problem.

I can mount my nfs on any client with those commands:

```
mount 192.168.0.3:/nfsroot /mnt

```

or

```
mount 192.168.0.3:/srv/nfs4/nfsroot /mnt

```

My /tftpboot/pxelinux.cfg/default config file is

```
DEFAULT vmlinuz-3.5.0-25-generic root=/dev/nfs initrd=initrd.img-3.5.0-25-generic nfsroot=192.168.0.3:/nfsroot ip=dhcp rw

```

I also tried 

```
DEFAULT vmlinuz-3.5.0-25-generic root=/dev/nfs initrd=initrd.img-3.5.0-25-generic nfsroot=192.168.0.3:/srv/nfs4/nfsroot ip=dhcp rw.

```

**What I got in initramfs:** 

With the setting [nfsroot=192.168.0.3:/nfsroot]

Diskless output:

```
mount call failed - server replied: Permission denied

```

On Syslog of my nfs server:

```
rpc.mountd[1266]: refused mount request from 192.168.0.10 for /nfsroot (/): not exported

```

With the setting [nfsroot=192.168.0.3:/srv/nfs4/nfsroot]

Diskless output:

```
mount: the kernel lacks NFS v3 support

```

On Syslog of my nfs server I got:

```

Mar 11 14:03:06 BootFromLan rpc.mountd[1266]: authenticated mount request from 192.168.0.10:834 for /srv/nfs4/nfsroot (/srv/nfs4/nfsroot)
Mar 11 14:03:06 BootFromLan rpc.mountd[1266]: refused unmount request from 192.168.0.10 for /root (/): not exported
