I recall someone warned that this issue would pop up with more (especially older) ethernet drivers. I was one of the people that ran into this on the em driver (Intel EtherExpress 100Mbit), which got a fairly prompt fix after I raised the issue. Since this is apparently caused by an interaction between the dhclient interface up/down detection mechanism and various wired ethernet interface drivers, it seems to me that it would help to be able to turn off dhclient's detection feature (or can we do that already?). The feature seems to be mostly useful for mobile devices (laptops and such) who tend to leave and enter different wireless network areas and need a new lease at that point. With wired interfaces, especially those that don't change physical location, the feature seems mostly pointless. Being able to turn it on or off at will seems useful and it would give other people running into this an easy way out.
