Bug#801629: asterisk: when run with systemd, asterisk no longer defaults to realtime or allows it to be configured

[James Bottomley]

Package: asterisk
Version: 1:13.1.0~dfsg-1.1+b1
Severity: normal

Under systemv init, asterisk is spawned by /etc/init.d/asterisk, which
checks the /etc/default/asterisk file and spawns asterisk realtime
(with the -p flag) unless the default is altered to AST_REALTIME=no

However, with the change to systemd, the default is no longer to spawn
with the -p flags.  Indeed, it's no longer configurable because the
whole lot is hard coded in the /etc/systemd/system/asterisk.service
as:

ExecStart=/usr/sbin/asterisk -g -f -U asterisk

Firstly, I think we need to put this back to the default of being
realtime unless requested not to, and secondly, I think we need to
respect the configuration options of /etc/default/asterisk.
Unfortunately, systemd is trying to phase these files out (by ignoring
them):

But according to the blog, there is still a way of importing shell
script like configuration files via the EnvironmentFile option, or by
spawning an actual script that reads the file.
