use case: Ubuntu 12.04 LTS using apache2
the code uses
sudo /etc/init.d/httpd stop
and
sudo /etc/init.d/httpd start
to stop & start the web server daemon. Ubuntu supports the service daemon and with an apache2 install the commands should be:
sudo service apache2 stop
and
sudo service apache2 start
the updater should detect which distro and version its running on and act accordingly
cat /etc/issue
The script is intended to be a skeleton/template, which is why it has so many comments about replacing commands. The suggested alternatives will not work with nginx or lighttpd. It is impractically complex to produce a script which runs correctly in every environment: instead, we have provided a very simple script which is easy enough to understand that it can easily be customized. See T4200 for discussion about why we do not maintain OS-specific packages, install/update/init.d scripts, etc., at this time.
