I use to work without mounting /usr and tend to copy all the things
I need to nfsroot. I do this because

* I have a separate /usr/share partition (so I would have to tweak
  fai_rc to export/mount /usr/share also). Note: the user space
  nfsd will export /usr/share automagically if you export /usr,
  the kernel space nfsd will not)

* Due to lack of space in /usr I have moved some stuff away and
  addressed these directories by symbolic links. These links point
  into void on the nfs exported directory.
  
So the motto "Just take the /usr of a typical linux system and
you have all that you need for fai installation" involves some
implicit assumptions. I don't think that it is more elegant
and less error prone to build a separate independant nfsroot
image.

Yes, I think, this is the right way to do it.

Kind regards, Thomas
