It's not quite that simple. I need to impose *two* security labels in
cachefiles_begin_secure() when I'm about to act on behalf of a process that's
tried to access a netfs file:
(1) The security label to act as. This is the label attached to the
cachefilesd process when it starts the cache. This is obtained by
cachefiles_get_security_ID().
(2) The security label to create files as. This is the label attached to
root directory of the cache. This is obtained by
cachefiles_determine_cache_secid().
