The want dependency is similar to the use dependency. If a service
script, for example called service1, adds "want service2" to its depend
function, OpenRC will attempt to start service2, if it exists on the
system, when service1 is started.
However, service1 will start regardless of the status of
service2.

This makes it possible to override settings in rc.conf by adding a
directory @SYSCONFDIR@/rc.conf.d and putting files in this directory.
The files will be processed in lexical order, and the last setting in
these files will be used.
The original way of doing this allowed users to change the supervisor in
conf.d/*. This changes this so that the supervisor setup can be done in
the service script itself.
