Re: [Xen-devel] openafs not supported?

[Kris Van Hees <aedil@xxxxxxxxxx>]

I haven't looked at it in detail yet (though I will), but I expect that OpenAFS
on Xen is going to need its own sysname target, rather than being able to just
use the i386 one.  I had to do the same when I did the port to UML (which was
actually fairly easy).

So, the possible options are that a new sysname target is needed (e.g. it could
be something like i386_xenlinux24, and so on), or the target for regular i386
linux may need to be extended to also operate for Xen, but that is less likely
to work well I think.
