Agree. Further, even if they're excessive *today*, they won't be 10 or 20 years from now. AFS is already older than that. Yeah, we may not need all 64 bits for a while, but for anything over 32 the right answer is 64._______________________________________________ AFS3-standardization mailing list [email protected] http://lists.openafs.org/mailman/listinfo/afs3-standardization
