This is good but what happens if there are no file SD targets configured? We'd still have to wait, no?

It's not fixing general lag I guess, this PR fixes just the lag of FileSD vs dns.

Ah sorry, I only gave a quick glance and I haven't noticed that, and I thought we were fixing a different kind of problem.

@bwplotka Could you explain what is the general lag?
It's bit hacky
Agree with you. I think it is a simple way to resolve the issue, and I don't find the general lag that you said.

Sorry, by general lag I meant the time between each DNS refresh (that is configured by flag). It's kind of flag as we don't watch for changes (as for DNS it's impossible), we poll every X seconds.
