Ted,

The list of AFS pioctls and the proposed alternatives for kAFS are
listed at

  https://www.infradead.org/~dhowells/kafs/user_interface.html

While it is true that the majority of the proposed xattrs are read-only
properties of AFS objects (cell, volume, fid, servers, sec_class,
sec_mode) there is one exception that is read-write (acls).  AuriStorFS
permits acls to be set per-file; there was some per-file acl work begun
for OpenAFS but it was never completed.

Is there an alternative for fetching and setting ACLs that should be
considered?
