[OpenAFS-devel] PAG support breaking non-afs group permissions on linux

[Troy Benjegerdes]

It appears that something related to being in a pag breaks unix group
permissions on non-afs files for the first group listed immediately
after the AFS pag groups.

I am able to reproduce this problem on x86 systems running linux 2.6.16
and various openafs versions in the 1.4.1-rc series, but not on a PPC
linux system.
