anvil/tools/anvil-manage-host

#!/usr/bin/perl
# 
# This tool provides a way to perform actions on a host that normally are handled by other processes, like 
# marking a system as configure, etc. This will likely grow constantly over time.
# 
# Supported switches;
# --mark-configured, --mark-unconfigured 
#   - Set / unset the 'system::configured' flag for the host.
# --database-active, --database-inactive
#   - On Striker, mark the local database as active / inactive
#
