Fixing the cron 'invoke-rc.d: action rotate is unknown, but proceeding anyway' warning

    For people receiving such a cron reporting via mail:


    Code
    1.

    you can avoid this by adding the --quiet invoke-rc.d option to the involved logrotate configuration files. For instance:

    Code
    1. root@jessie64:/usr/local/src# grep -nr 'invoke-rc.d.*\srotate' /etc/logrotate.d/etc/logrotate.d/rsyslog:10:invoke-rc.d rsyslog rotate > /dev/null/etc/logrotate.d/rsyslog:35:invoke-rc.d rsyslog rotate > /dev/null

    So here, in the file /etc/logrotate.d/rsyslog, you must modify the invoke-rc.d rsyslog rotate > /dev/null statements as follows:

    Code
    1. invoke-rc.d --quiet rsyslog rotate > /dev/null

    You must process same way for any logrotate configuration file for which the warning mentionned above is raised.


    This behavior is due to the fact that i-MSCP interfaces with the invoke-rc-d command through the policyrcd-script-zg2 package, hence policy-rc.d layer.


    This issue has been fixed lately in the init-system-helpers package v1.47 (Debian >= 9.0, Ubuntu >= 17.04). Thus, affected people should be those that are using either Debian Jessie, Ubuntu Trusty Thar or Ubuntu Xenial Xerus.:


    Code
    1. init-system-helpers (1.47) unstable; urgency=medium
    4. [ Christian Hofstaedtler ]
    5. * Align policy-rc.d existing/nonexisting case for custom actions.
    6. Previously, when calling invoke-rc.d with a "custom" action, it
    7. would print an error when a policy-rc.d file was installed, but
    8. it would be silent if no such file was installed. (Closes: #728682)
