"Almost" is the keyword here.

The default hobbitlaunch.cfg is created when Hobbit is compiled, and
therefore some of the environment settings can be determined by the
configure-script and put into the standard environment settings in the
hobbitserver.cfg/hobbitclient.cfg files.

For a client-install, that is not the case. You typically build the
client on one box, then copy the installation to all of the others
running the same OS. So when starting the client, you need some
run-time code to pick up e.g. the hostname of the box. runclient.sh
does that.

You shouldn't put any settings in runclient.sh - add them to
hobbitclient.cfg.

You could run the "runclient.sh" from hobbitlaunch.cfg, but that would
just start a second instance of the hobbitlaunch program - one for the
server part of Hobbit, and one for the client part. Seems a bit wasteful
to me, so I did it the other way around.

Done.
