## If you installed ForwardXMPP in a virtualenv, you will probably want to
## override this line so the executable is the python inside your virtualenv.
## If you did not install ForwardXMPP system-wide, you can set
## Environment=PYTHONPATH=<directory of your source checkout>
## and this ExecStart should work.
ExecStart=/usr/bin/python3 -m forwardxmpp --config-file /etc/forwardxmpp/config.ini

## Generally the only privileged operation ForwardXMPP needs to do is read
## its configuration file (which has a password in it). If DynamicUser can't
## read it, you can turn that off and set a low-privileged static User.
