Last change on this file since 1329 was 1274, checked in by mitchb, 15 years ago
Upgrade OpenAFS to 1.4.11 o Two of our patches (postinit and pts-encrypt) have been upstreamed o Two deltas we applied (dprintf-rename-20090427 and linux26-defer-cred-changing-20090511) are now included in this version o The scripts patch has some context adjustments o Our spec file patch corrects an upstream bug which tries to install a compile_et manpage, which conflicts with e2fsprogs-devel
