OK.  you should know that the stability comes from linux itself
and the underlying user-level packages, which have nothing to do 
with the distro (any of them).

well, the thing about nfs root is that there's almost no installation,
per se.  if you wanted, you could boot the nodes off a live master's 
root filesystem.  normally, master and node images are kept mostly
separate, though, because it's handy to avoid entangling them
(ie, you may not want mysql-server installed on compute nodes, but 
only on the master, etc.  or just different versions.)
