This seems like a good suggestion.

This bug deals with virtual interfaces triggering a "SIOCSIFFLAGS: Cannot assign requested address" warning, while still succeeding, and can be remedied by removing or patching the /etc/network/if-pre-up.d/wireless-tools file.

I've created Bug #351378 to track the issue where DHCP fails to work for a virtual interface, when a DHCP client is used directly, or indirectly via the /etc/network/interfaces config file, and is unaffected by the /etc/network/if-pre-up.d/wireless-tools file.

The two bugs may have a common underlying cause, but superficially they have different symptoms.
