Oh to be so lucky.

Matlab barfs all over '@sys' refs.  I'll tell our users
they may get lucky :)

RHELv5 amd64_linux26 + OpenAFS 1.4.6

/afs/rcf.our.org/apps/Matlab/@sys/R2009b/bin

This does not happen on the following other hosts we've tested:

    RHELv5 amd64_linux26 with OpenAFS 1.4.7
    RHELv5 i386_linux26 with OpenAFS 1.4.11

How do we get the AFS client to stop converting 'amd64_linux26'
to '@sys' ?

It's not the AFS client. It's the fact that you have more than one
path to the same vnode; Someone references it via @sys, and the kernel
caches the dentry with the path @sys. You get one dentry per inode.
Unless we find a way to implement dentries that effectively point to
alias inodes, and we haven't yet, that can happen.

It's not new. It's just "luck".

Is this something changed post-1.4.6?
