Public bug reported:
When installing dual stack IPv4 and IPv6 DHCP I found that DHCPv4 and
DHCPv6 clobber each others /run/dhcp-server path when you stop or
restart one of the daemons
I found that the config in the systemd unit has the /run path set to the
same location for both DHCPv4 and DHCPv6

Thanks Jamie,
Ah, cool, so that ufw config is when the install is a client.
I am having issues with the install as a DHCPv6 server.
I will revert the UFW changes I have made and add in a new
/etc/ufw/application.d/dhcpd config to allow the install to run a DHCPv6
server
Thanks
