I have problems with a slow shutdown. I followed the instructions to reduce the timeout.
EOS 5.1

I set the timeouts to 9 seconds as answered below but it does not work.

Then run this command to reload

systemctl daemon-reload

The only workarounds that seems to work are:

  • Set DefaultTimeoutStopSec to 10 or lower, or
  • Kill cerbere before shutdown
