Arch Linux

Description:

The current prosody.service file makes use of "prosodyctl" as root:

```
ExecStart=/usr/bin/prosodyctl start
ExecStop=/usr/bin/prosodyctl stop
ExecReload=/usr/bin/prosodyctl reload
```

Those commands are not recommended (and running "prosodyctl reload" manually will even print a big warning). Running prosodyctl to start prosody also has the unfortunate effect of letting prosody drop privileges itself, and preventing any systemd unit hardening.

```
WARNING: Use of prosodyctl start/stop/restart/reload is not recommended
if Prosody is managed by an init system - use that directly instead.
e.g. systemctl reload prosody
```

The prosody-hg AUR package takes a different approach that is more integrated with systemd: https://aur.archlinux.org/cgit/aur.git/tree/prosody.service?h=prosody-hg

Additional info:
* package version(s): 0.11.8-1 (all of them)


Steps to reproduce:

* Install prosody
* Try to harden a bit the runtime conditions and fail
