I think that Doug is trying to say that our default location should be /usr (not /usr/local/ofed). That would seem to solve several issues:

- will automatically generate conflicts with the RHEL OFED RPMs
- less muckery with finding libraries and header files
- can claim to be FHS complaint
- user *can* change the default location to elsewhere if they want to

If it's a simple issue to change our default, is the only reason *not* to do it the historical precedent of prior community OFED versions? If so, that argument is somewhat diluted because a) we (as a community) are encouraging users to upgrade, and b) RH started is already shipping OFED RPMs that live in /usr.

I think you're missing Doug's point. There is currently no mechanism
for the user to know that they're installing 2 potentially
conflicting versions of the same software (OFED).

That's a good point, although not entirely correct. AFAIK OFED installer currently attempts to detect and warn about conflicting libraries, this
logic probably can be improved.



Quoting Jeff Squyres <[EMAIL PROTECTED]>:
Subject: Re: [ofa-general] OFED 1.2 Feb-26 meeting summary

That seems like chasing our tail: adding more logic/work to replicate a mechanism that is already available (*and* making sure that we keep
this logic up-to-date with all the OFED distributions out there --
which seems like a losing proposition).  RPM can detect this kind of
conflict and prevent it.  Why aren't we using it?

Oh, right, because we're doing several kinds of non-standard things
that preclude us from doing so.  :-)

Right. But the user *can* the prefix to /usr, and RPM will detect conflicts
then, isn't that right?

This is a joke, right? You can't *really* be serious. If you are, then
I suggest the EWG change the acronym for OFED to Open Fabrics
Experimental Distribution because no enterprise customer I know of would accept the above suggestion that they change the spec file and recompile
just to get RPM to do its job as reasonable for an enterprise software
package.
