Bug#408708: Installation of asterisk-config before/without asterisk package will not create the asterisk user

[Diego Iastrubni]

This will not happen Tzafrir. From Debian policy manual, 9.3.2:

The /etc/init.d scripts must be treated as configuration files, either (if 
they are present in the package, that is, in the .deb file) by marking them 
as conffiles, or, (if they do not exist in the .deb) by managing them 
correctly in the maintainer scripts (see Configuration files, Section 10.7). 
This is important since we want to give the local system administrator the 
chance to adapt the scripts to the local system, e.g., to disable a service 
without de-installing the package, or to specify some special command line 
options when starting a service, while making sure their changes aren't lost 
during the next package upgrade.
