Netplug is a daemon that responds to network cables being plugged in or

useful for DHCP-managed systems that move around a lot, such as laptops
and systems in cluster environments.

Thank you, thank you, thank you. I was just thinking today how
annoying it is that whenever I boot up my laptop, dhclient runs and tries
to get an IP address on the ethernet interface until it's ^C'd. Since
I often use the Ethernet interface this is not a bad default, but dhclient
can't even realize on its own that there's no cable plugged in.

Hmm, that seems to raise the question - why doesn't dhclient just handle
that? On a DHCP interface, it's running anyway. if it paid attention
to link status, it would know when to re-request an IP. If you are
statically assigned, you don't really care anyway.
