I fail to see what has systemd has to do with anything here... this is either a problem with Ubuntu's package or an old kea which just doesn't support SIGHUP maybe?
FWIW, kea 1.2.0 on CentOS 7.4 processes SIGHUP fine: [root@dhcp01 ~] # rpm -q kea kea-1.2.0-1.el7.centos.x86_64 [root@dhcp01 ~] # ps fax | grep -v grep | grep kea 1060 ?
