nfsroot boot long pause

[Jimmy Stewpot]

Hello,

I have been working on setting up an nfsroot system so that I can have a 
training environment easily mounted remotely. One of the issues I am 
having is that when the kernel boots it brings up the interfaces then 
there is a very long pause before it mounts the nfsroot. My pxelinux 
syntax is as follows

label ubuntu-nfs
   kernel ubuntu-installer/vmlinuz-2.6.24-16-server
       append initrd=ubuntu-installer/initrd.img-2.6.24-16-nfs 
root=/dev/nfs nfsroot=<server ip>:/builds/ubuntu-nfs,nolock 
nfsaddrs=::::::dhcp


The pause seems to vary from between 2 minutes and 7 minutes. I thought 
that may have been because it was waiting for portmap or something  like 
that but I am not 100% sure. Any additional advice or feedback would be 
greatly appreciated.

Regards,

Jimmy.
