Agreed, good catch!
That's actually probably one of the bugs (if not *the* bug) mentioned in
the old mail.

Hello,
Considering the target of user-level drivers, I've come to a few biting
points:
- we should have a PCI arbitrer in the end.
- that arbitrer should permit to confine drivers to resources of only
one PCI device, no more (though of course with DMA, without IO-MMU,
you could access anywher

That depends on what one means by "valid". You're right about chown
of course, but it's not clear that POSIX absolutely prohibits getuid
from returning (uid_t) -1. And even if POSIX did prohibit that,

That doesn't read correctly. You are correct t
I think you can portably detect the failure case with the errno=0 method,
rather than relying on #ifdef.

If we really want to support that, there would be
a lot of other coreutils code that would need fixing,
no? For example, the command
chown 4294967295

I'll take that as an ACK ;-)
Pushed.
