There's no real standard on configuration files in Unix.
So you can do whatever you want within reason.

/etc/infiniband is an OFED thing.
I suggest keeping libsdp separate so that it is
distribution agnostic.

In the past, lots of customers asked that installed files reside
under $prefix. It *is* important since it lets people
find out easily what is added to their systems.
OFED does not follow this rule 100% but its better not to
add more exceptions.

So installed file hits a different location
depending on date and on whether I have an old library installed?
This pretty much guarantees user won't be able to find the file you have
installed: you seem to assume that users read installation logs but that's
typically not the case.

Why not just have libsdp.conf.example, or something like that, under $prefix/etc
and install that always, and only copy to $prefix/etc/libsdp.conf
if that does not exist?
