Depending on the exact configuration some of these boxes may not be available; nevertheless, those missing can be imported from other network locations.
Beware that once a system box is forgotten, there is no way to get back to it (unless it is also exported by the system to the network). This is not a problem since a new namespace starts with a standard set of system boxes imported to well-known prefixes.
Appart from the set of boxes supplied by the system, there is a set of conventions that are important for system operation. The conventions are changing quickly since Plan B is just born. Therefore, you should expect that most of the boxes shown in this section are likely to change as experience with the system is gained.
As of today, this is the typical hierarchy of boxes found in a name space:
Those under /b are boxes from the local kernel. All other ones are prefixes where some other boxes (including the local ones) may be mounted. For example, /bin is usually a set of imports from either local /b/fs/bin boxes or from network boxes advertised as /bin.
