I think the tar problem you're seeing is a manifestation of a known bug in
AFS. It shows up under SunOS, HP/UX, and AOS. If you attempt to call open()
on an existing file whose Unix mode bits allow writing but not reading, and
if you use open() flags O_WRONLY|O_CREAT, the open() fails with errno 13
(EACCES). On Unix filesystems, the open() succeeds, as it should.
I don't know specifically how tar opens files, but your symptoms seem to match
those that tickle this bug.
