NFS-root doesn't scale too well, the implementation of NFS in Linux is
quite chatty.
Someone else responded to this, and expect even more scalability
performance with NFSv4...lots more ;)
I'll take your word for it that they have a version tracking mechanism.
Take my word that if you're going into larger installations with the
least amount of non-homogeneity you'll want to at least read about, if
not use, such mechanisms :-)
Well, "large" is relative, if I have a 32k core cluster with all
identical HW, all I really need for this "large" installation is a
single image.. It's the diversity that kills that then requires tight
version/config tracking, even if all the images are managed from a
single point..but that's trivial common sense ;)
