NFS Tips with user mode Linux

If you use slirp to provide networking to your UML (User Mode Linux) and you want to mount your host directories in your uml machine remember to:

1. Compile the uml kernel with nfs support
2. Export the filesystem using : the "insecure" option. i.e.: /directoryXX host(ro,insecure).
This is necessary since in user mode you cannot bind to ports under 1024.
3. Mount the filesystem using the IP of your host machine and include the nolock mount option.
