On a laptop I have defined a PPPoe connect (xDSL). When booting in a place where
this isn't available it tries to connect for ~35 seconds before giving up with
error. When it connects it's in less than 5 seconds usually.

Please lower the timeout for giving up. I realize though that for bad
connections the 35 seconds might be good. If you believe this is a good default,
how could I lower it manually in order to boot faster in all places?

Thanks
