I tried it with Beta 1.1 but couldn't get the settings right for fstab and cmdline.txt.

Are there any people who succeeded in doing this?

NFS boot is not such a big success story as it mostly looks reading internet, already CurlyMo's Alpha5 was able to boot NFS with few small mods. Since early Beta development it was a feature and I was using it until switch to btrfs which provided for me similar targets even more.

I will check the actual status with all the changes for past months get back to you.

But as insights general requirement is:
1) kernel with auto ip configuration
2) correct kernel command line options (ip= for kernel auto ip, root=/dev/nfs, nfsroot=10.0.0.10:/path/to/root,nfs_mount_options, bug-free networking scripts - some versions of Debian used to ifdown & ifup already UP network with rootfs mounted on it ... bad bad)
3) with NFS3, nolock is a must as mount option (you don't have rpcbind & statd available during mount) - with NFS4 it's much more straight forward
4) nfs export from server with no_root_squash
5) the NFS should contain simple copy of your system, rsync or even cp -arvd will do just fine

Like I said, will recheck later today and post mini-howto.

Thank you very much for replying more in-depth! I tried following these guides:

http://cellux.github.io/articles/moving-to-nfs-root/
http://www.raspberrypi.org/phpBB3/viewtopic.php?f=63&t=5974

However I didn't succeed, and gave up because I thought that my NAS's NFS daemon might not be 100% reliable (my NAS has built-in NFS where I have no control over all parameters). I'll try again coming week. However, it would also be nice to know if somebody else succeeded because I couldn't find any success stories about this with XBian. That's also why I asked - to know whether it was worth trying

Also - the layout of the fstab was a bit different than I was used to (it used LABEL=, @root etc), and the guides I read didn't cover changing that. That's also why I asked.

So it would be great if you could write something about the XBian-specific parts of achieving this, and the requirements
