Comment 1 for bug 1598856

/etc/sysconfig and /etc/default are kind of legacy.

As a quick fix, the unit file should read /etc/sysconfig/tids as an EnvironmentFile.

As a proper fix, tids should:
* look for an activated socket and use it
* look for a config file and load it (optional)
* if not overridden by config, use the system fqdn as the GSS name and listen on all addresses[1]
