[Bug 1331891] Re: [systemd] /etc/logrotate.d/rsyslog fails to reload rsyslog

[Anders Kaseorg]

This needs a further tweak.

# service rsyslog reload
Usage: /etc/init.d/rsyslog {start|stop|rotate|restart|force-reload|status}
# zcat /usr/share/doc/rsyslog/NEWS.Debian.gz 
rsyslog (5.8.1-1) unstable; urgency=low

  The way rsyslog processes SIGHUP has changed. It no longer does a reload
  of its configuration, but simply closes all open files, which is a much more
  lightweight operation.
  To apply a changed configuration, rsyslogd needs to be restarted now.
  As a consequence, the reload action has been dropped from the init script.

  A new action called "rotate" was added to the init script, which signals
  rsyslogd to close all open files. This new action is used in the rsyslog
  logrotate configuration file.

# service rsyslog rotate
 * Closing open files rsyslogd                                           [ OK ]

See also https://bugs.debian.org/626365. The right action is ‘service
rsyslog rotate’, not reload. Sorry for not catching that earlier.

Title:
  [systemd] /etc/logrotate.d/rsyslog fails to reload rsyslog

Status in “rsyslog” package in Ubuntu:
  New

Bug description:
  /etc/logrotate.d/rsyslog contains

          postrotate
                  reload rsyslog >/dev/null 2>&1 || true
          endscript

  which works on Upstart but not on systemd. Therefore, after logs are
  rotated, rsyslog continues to write to the old files, leaving the new
  files empty. It should be changed to ‘service rsyslog reload’ or
  ‘invoke-rc.d rsyslog reload’ or something.
