Bug#707892: don't assume apache2 is running 24 hours a day when rotating logs

[jidanni@jidanni.org]

Package: apache2
Version: 2.4.4-2
File: /etc/logrotate.d/apache2

Gentlemen,

   /etc/logrotate.d/apache2
   /var/log/apache2/*.log {
   ...
           postrotate
                   /etc/init.d/apache2 reload > /dev/null

will always fail,
and will always send root email every single day:

   From: Anacron <root@...>
   Subject: Anacron job 'cron.daily' on jidanni2
   To: root@...

   /etc/cron.daily/logrotate:
   error: error running shared postrotate script for '/var/log/apache2/*.log '
   run-parts: /etc/cron.daily/logrotate exited with return code 1

if the user does not choose to start apache2 at boot.

I.e., the user has apache2 installed, but does not choose to run it all
day long.  (Using sysv-rc-conf to disable it.)

Therefore you need to make sure you don't return an error in the case it
is not running p l e a s e!
