invalid reopen-logs command in php5-fpm

[Matt LaPlante]

The php5-fpm package includes the following logrotate script:

/var/log/php5-fpm.log {
        rotate 12
        weekly
        missingok
        notifempty
        compress
        delaycompress
        postrotate
                invoke-rc.d php5-fpm reopen-logs > /dev/null
        endscript
}

However running this on 14.04.1 produces an error:

initctl: invalid command: reopen-logs
Try `initctl --help' for more information.
invoke-rc.d: initscript php5-fpm, action "reopen-logs" failed.
error: error running non-shared postrotate script for /var/log/php5-fpm.log of '/var/log/php5-fpm.log '
