/etc/init.d/dot-config can save information e.g. that it failed to get
dot-config form the given URL. However, apply_dot-config called from
/etc/init.d/dot-config overwrites this information by the result of checking
the dot-config. The checking of the dot-config has to be done also in
apply_dot-config, because the webinterface writes down changed dot-config and
executes only apply_dot-config.
