[...]    
    I've just got a couple comments on this.
    
    * The gentoo-sources patches are almost all upstream and based on the
    W.X.Y.Z "stable release" patchsets, except for 2-3 cases that probably
    aren't relevant to clusters. As a result, Gentoo folks would be
    reasonably well off just running vanilla-sources, which groups them in
    with everyone else wanting Lustre on a vanilla kernel.

Fair enough.  If the solution to how to run lustre on a gentoo system starts
with "run a vanilla kernel, not a gentoo kernel", that makes things
considerably easier.  It doesn't make all the problems go away, but at least
you've removed one of the uglier dimensions from the task :-}
				 
    * Normally I would recommend hardened-sources for anything resembling a
    server, but you should have all your nodes and file servers blocked off
    from the Internet anyway so that's a non-issue.
    
Yes.  I expect that most of our machines will not be having ports open on the
big-I internet, at least in the early days.  Later, that may change, and those
network-security patches will be of more immediate interest to us.

Of somewhat more interest, even early on, are patches for file-system
security.  Last I paid attention to it, the plan was to pull in that class of
patch on an ad-hoc basis as we decide they're justified.
