Hi,

That specific 8.10 test failure is addressed separately upstream.
I'm leaving this bug open to record the df behavior you detail above.
It triggers when df can't read the list of mounted file systems
(why can it not on your sparc system?)

We may try to match the output of statfs() in this case,
and if no direct match, then fail?  I'm not sure.

cheers,
Pádraig.
