I just tested the new Webmin 1.540, and in the Bootup and shutdown module, just like with the previous version, it still does not show/edit most of the services correctly.
All services that use Upstart style configurations are shown as "At boot: no" even though they are started through Upstart.
Trying to stop them results in the warning:
Executing /etc/init.d/mysql stop .. Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service mysql stop Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the stop(8) utility, e.g. stop mysql mysql stop/waiting
Setting "At boot" to "no" has no effect, since the Upstart config file in
/etc/init is not modified.
