Yes, OpenAFS caches all data, regardless of whether it's readonly
or read-write. For RW data, the cache manager maintains a callback
for each individual file, whereas readonly data only requires a callback
on the volume. The fileserver will notify the clients when a file changes
so the client can pull down the new version on the next access.
