PSA: unattended-upgrades restarted nginx in the middle of my stream (lemmy.world)

Small thing but it got me last week. I relay my stream to twitch through nginx-rtmp on a cheap VPS, and one morning unattended-upgrades pulled a new systemd, needrestart restarted nginx (and postgres, and everything else) and the stream dropped. OBS reconnected fast but twitch counted it as two streams.

default timer is 06:00 UTC + up to 1h random, which is exactly when I stream lol. moved it with a drop-in:

# systemctl edit apt-daily-upgrade.timer
[Timer]
OnCalendar=
OnCalendar=*-*-* 13:45:00 UTC
RandomizedDelaySec=15m

the empty OnCalendar= matters, without it you just add a second time and keep the old one.

anyone else got bitten by this?

I mean, unattended upgrades has it's own config file where you can specify when to schedule a reboot (when needed), which you'd usually do in off-hours like 2 AM your local time, so changing the Systemd unit activation time seems like the wrong fix.

Edit: Nevermind, your issue was that the daemons were being rebooted, not the whole system, if I understood that correctly

    yeah exactly, no reboot, it was needrestart restarting nginx and postgres after the systemd update. you're right that the timer is kind of the blunt fix, the cleaner one is probably telling needrestart to only list instead of restart ($nrconf{restart} = 'l' in needrestart.conf), or excluding nginx from it. I went with the timer because I still want things restarted, just not while I'm live
