Hello NSD folk, In the Linux world, the major distributions (RedHat, CentOS, Debian, Ubuntu) are switching from the traditional init to systemd. Systemd provides some interesting features, one of which is to hook into the message bus, so that applications can notify it of events. It would be nice if NSD were to support systemd. In particular, if NSD could signal systemd that it had started up, that would make it easier to manage. In particular, NSD should emit the "ready" signal after it has read the nsd.db file and started listening for DNS queries, so that systemd can invoke other apps that depend on NSD running fully (think monitoring, OSPF and BGP as examples). The folk at CZNIC have done some work in this area, so I hope they don't mind me pointing to their work, so that the NSD devs have a good reference point. https://gitlab.labs.nic.cz/labs/knot/commit/bdb46f5e0687a649da3e86cbbb66b6c261ae574e Regards, Anand
