linux-fai Digest, Vol 31, Issue 1 | problem mounting nfs

[Augustine Ike]

Which FAI document did you read on this? I found the old documentation
rather confusing but the revised one is better. See this
http://www.informatik.uni-koeln.de/fai/fai-guide/.
That said, have you build your mirror or are you using the one from
debian? I found building my own mirror before running fai-setup worked
best. "I also hope DNS, DHCP etc are all setup correctly and the
necessary files in /etc/fai are also fine".
A detail break down of this configs will be helpful. Your error should
be resolved if your FAI parameters and mirror is fine.
