DHCP Lease Monitor for OpenBSD (written in Rust)

This is a daemon that monitors any lease changes for the specified interfaces. When a change happens it then calls a script located in /etc/dhcpleasemon. The script name should be:

lease_trigger_<interface>

The script has access to the following environment variables:

• $DHCP_IFACE -- interface name
• $DHCP_IP_ROUTE -- default route for the interface
• $DHCP_IP_ADDR -- IP address from the lease
