nvoke-rc.d rsyslog rotate > /dev/null [](start = 9, length = 37)

in /etc/init.d/rsyslog, rotate is doing the kill HUP. why not use invoke-rc.d rsyslog rotate?

It was not working properly. It was confirmed as a bug present in our version of init-system-helpers: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=672218.

There seem to be two workarounds:

  1. service rsyslog rotate >/dev/null 2>&1 || true
  2. kill -HUP $(cat /var/run/rsyslogd.pid)

I have tested the latter solution. I did not try the former, as the || true seems a bit hacky. I can test it if you'd like.

kill -HUP $(cat /var/run/rsyslogd.pid)
endscript
}
