@MrZammler:
The nfs-server for linux actually comes in both a user-space and kernel-space version - the former doesn't need any kernel support and is a bit less efficient, but in this case, it will definately not matter.
For example - in debian the packages for these different nfs-servers are called "nfs-user-server" respective "nfs-kernel-server" and I suspect it is quite similar in other distributions.
