IBM AFS 3.6 patch ... something from last year on Solaris 9
SPARC (sun4u) 64-bit mode.

or

OpenAFS 1.4.2rc1 on RHELv3 SMP i686

or

OpenAFS 1.4.3 on RHELv4 uniprocessor i686

No.

OpenAFS 1.4.2 on Solaris 9 SPARC (sun4u) 64-bit mode

And "No"

We *may* have a 1.4.4 RHELv5 box.  I'll look.

No.

I'm not in a position to do that.

The former reports:

It updates the Last Update info properly.
