Package: rsyslog
Version: 8.2302.0-1~bpo11+1devuan1

The rsyslog-rotate script installed by rsyslog from chimaera-backports
is missing the conditional call to invoke-rc.d, and thus fails to HUP
rsyslog after log rotation if systemctl is not present.

i.e. the section:

   else
       invoke-rc.d rsyslog rotate > /dev/null
   fi

(as seen in rsyslog from chimaera) is missing from this version of the
script.
