sysdb
=====

sysdb is a simple database holding information relevant to system deployment,
including

#. a MAC to FQDN mapping

#. whether to boot from local disk or install

#. if installation is requested, which distribution/release to install

#. which environment a system belongs to, and who can manage the environment

#. arbitrary key-value pairs which can be used to store additional information
   like the Puppet role of a system.

sysdb runs on the boot server, ie. ``boot00.psi.ch`` (production) and
``boot00-test.psi.ch`` (testing).
