I think you're seeing a manifestation of a known AFS bug; the description in
my notes is this:
This shows up only under SunOS, HP/UX,
and RT-AOS. If you attempt to call open() on an existing file which has
Unix mode bits set to allow write permission but not read permission
(e.g., --w--w--w), and if you use open() flags O_WRONLY|O_CREAT, the
open() fails with errno 13 (EACCES). Under UFS, the open() succeeds.
This was discussed here in February, in a thread titled "A question on
protection semantics". At that time, I posted a short program which
demonstrates the bug. Let me know if you don't have access to posts from
February, in which case I'll send you the relevant postings.
