dCache SRM2.2

There was a dedicated dCache session during CHEP for discussion between site admins and the developers in order to discover the latest developments and get help in the server configuration, which is *difficult*. Link groups and space reservations were flying about all over the place. More documentation is required, but this seems to be difficult when things are changing so fast (new options magically appear, or don't appear, in the dCacheSetup file). A training workshop would also be useful...
