After a Debian Unstable upgrade a couple of months ago, dhcpd (from
the isc-dhcp-server package) would no longer start automatically. This
is because it relies on a sysvinit startup script, and systemd has
finally removed support for that.

Looks like upstream development of that project has largely ceased, in
favour of a more elaborate successor that I am in no hurry to switch
to, for my simple home-internal needs. You can actually manually
launch /usr/sbin/dhcpd as root and it will automatically fork a daemon
process, but this got a bit tiresome. So I created a systemd service
definition for it:

    [Unit]
    Description=ISC DHCP Server

    [Install]
    WantedBy=network.target

    [Service]
    Type=forking
    ExecStart=/usr/sbin/dhcpd
    TimeoutStopSec=5
    Restart=always

That’s just under a dozen lines, including blank ones -- not a bad
replacement for a sysvinit script that is nearly 200 lines in size ...
