The After=syslog.target is unnecessary these days and should be removed
to keep things simple.

Is this really necessary? $HOME is something that should be set
according to the user something is run as. And it should be set in the
same code that drops the privileges.

We now default to syslog logging, so I can only recommend to drop this
line here, in order not to override the system-wide setting.
