A new command in vspadmin writes the default config file for a new vspd
deployment. The behaviour is removed from vspd and documentation has
been updated to reflect the change.
vspadmin is a new binary which implements one-off admin tasks which are
necessarily interactive and thus do not fit neatly into the long-lived
vspd binary.
The first behaviour added to vspadmin is the ability to create a new
vspd database. This behaviour is removed from vspd with the associated
config option deprecated. Documentation and scripts updated to reflect
the change.
