[Grml] Failure mode testing (network)

It can be annoying to run grml without a network. When you unplug ethernet and boot grml, various 'strange' things happen. Name resolution and network time fail. That is normal, but the problem is retry/timeout settings. After a couple of minutes the daemon error messages should stop. Some reappear for long periods of time.

Suggestion: test grml in this 'failure' mode and adjust the retry/timeout factors. Sometimes, even when you have a working network, the name resolution system is down, giving a similar result.
