just pushed
https://github.com/grml/grml-live/commit/950ef7ae57fce8dea86b13544242b0249cec257a
its the same patch, just slightly different closes line

Patch looks good, ACK from my side, feel free to push to master.

I propose the following fix:
 https://github.com/evgeni/grml-live/commit/1f5d8fe463381b2c42c75d7f951dd27272548cb9

isn't it "ethdevice-timeout" instead of "ethtimeout"?

I tried to submit this according to the instructions at
  http://grml.github.com/#patch
but the mail bounced. That documentation appears to be wrong,
it needs to explain how to format the subject line for sending patches.

mention the ethtimeout option, currently mentioned only in a blog entry
 http://grml.supersized.org/archives/337-More-robust-network-booting.html
