[ewg] Re: [ofa-general] OFED 1.2 Feb-26 meeting summary

[Jeff Squyres]

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.
