The server is configured to top working in 24 Hours from the time it was
initially started. To modify this value, please see the ``--timeout``
parameter.
The hangar server directory layout, contents, and access conventions are
similar, though significantly different enough to the regular user "client"
implementation that it is not possible to fully access all information via
regular API methods. These changes occur as a result of the uniformity of
operations promised by both the RPC structure and negotiations between the
client/server upon connection.
More simply put, we know more, so we can optimize access more; similar, but
not identical.
