No, it doesn't look like the venus implementation for CODA_READDIR has
returned EOPNOTSUP or something similar for a long time and doesn't even
exist anymore in the copy of coda.h that I'm looking at.

The CTL_FILE is the Coda alternative to adding additional entries to the
syscall table. We use it as the entry point for ioctls that pass user
credentials and to set/query acls, quota, volume information and other
stuff. In other words it is used by clog, cfs, and repair to have a
reliable/authenticated way to pass messages to venus.
