MMDVMHost Systemd setup
=======================
Preface
-------
Since moving to Systemd many admins are struggling with the differences, in an effort to take the work
out of installing MMDVMHost on your linux host, I have written a service handler and the related systemd
unit files.
I hope these help you get going quickly.
Written on / tested on / confirmed working on Raspbian Jessie-lite but should work just fine on any
system using systemd.
Enjoy, 73 de MW0MWZ
Install Instructions
--------------------
1. Copy mmdvmhost_service to /usr/local/sbin
2. Change the permisions of /usr/local/sbin/mmdvmhost_service to 500 (root executable)
3. Change the variables in /usr/local/sbin/mmdvmhost_service to match your setup
(MMDVMHost.ini location, log location, user and daemon location)
4. Copy mmdvmhost.service to /lib/systemd/system
5. Copy mmdvmhost.timer to /lib/systemd/system
6. Edit the timeout in mmdvmhost.timer to suit - 45 secs is a reasonable starting point.
7. Reload systemctl with: "systemctl daemon-reload"
8. Add the timer serice to the boot with: "systemctl enable mmdvmhost.timer"
**NOTE - There is no need / desire to enable mmdvmhost.service!
