I have a working PXE boot of Knoppix but I am seeing some a problem with NFS.

This works from the CD boot
1) Load knoppix with config and HD image from hda3
2) Mount an NFS share to /work (I am forced to recreate /work each time)

What I want
1) Boot from network with config and a custom HD image (without any local HD)
- I need a specific user with their home dir setup
2) Mount the NFS into /work

Problem:
When I boot from the network my NFS share is ALWAYS 'readonly' even though I configured it as 'rw' (it works fine when booting from the CD)

Question: What should I check to find the problem?

Second Question: Is it possible to have a custom HD image when there are no local HDs?

Thanks,
Jack
