Hi Andreas,

I did do a little more due diligence:

These are the headers directly #include-d by our "utility"

that live in the lustre tree.  They likely pull in several more.
As I said elsewhere somewhere, unless the libcfs, lnet, lustre and utils
components of lustre know that these are exported via an unambiguous
mechanism, installing only the minimal subset will be prone to problems.
A better way is to have them stage the headers and run a validation that
they are all both self-sufficient and idempotent, meaning that any
requisite headers are also staged and they are all guarded with duplicate
inclusion guards.  This can be done with a trivial script.

I can make this part of the "lustre-devel package" project.  I was trying
to limit scope by installing everything in sight.  At least for now.
