Well, it doesn't... SuSE helps SuSE users. And I'm not being glib,
that's just how it works.

xfs.org is a public wiki run by a 3rd party, so I can't speak to the accuracy
of statements made about support agreements between SGI & SuSE, if any.
So I guess I have no useful insight there.

You're welcome to be interested all you want, but availability of support
from either SGI (not related to CentOS at all), upstream (focused on new work,
not older distros), or Red Hat (who sells support, vs. gives it away, in
order to pay the people to keep maintaining the distro that CentOS is
more than welcome to pick up, rebuild, & ship, and support or not as *they*
You'll find that you usually get very good support for XFS issues & questions
related to near-current mainline kernels. But people who can spend time
& effort supporting free distros containing custom codebases are going
to be few & far between.
The closer you get to mainline, the more willing & able the developers
will be to help you out. The further you get into custom distro kernels,
the more it becomes the responsibility of that distro - CentOS, in your case,
and they pretty explicitly tell you what you can expect for support from
I'm not trying to be flippant or glib or antagonistic here, that's just
the way things are structured; you chose CentOS, and "CentOS is designed for
people who need an enterprise class OS without the cost or support of
the prominent North American Enterprise Linux vendor."

(Ok, mainline; I was just differentiating between RHEL & Linux.)
