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?

same here on the reboots, I never let it reboot on its own either. for me the reboot wasn't the problem, it was needrestart bouncing nginx and postgres right after the upgrade, which you only notice if something long lived is running at that moment, like a stream lol
