I'm terribly sorry.  this is a sign that accountants have eaten
the brains of your IT heads.

HPC clusters are normally a horde of clones.  no configuration change
is applied individually to a node, but rather applied en-mass.
reimaging nodes is not a huge big deal, for instance (and a non-event
if you use nfs-root - definitely a good idea in some cases.)
