I've tracked down a wicd problem to something related to this, I think. Acquiring a DHCP lease manually works correctly, but wicd drops the lease immediately after connection, when using both dhcpcd and dhclient.

Slightly cleaned output from /var/log/messages.log immediately after a reconnect order via wicd follows below.

Note that dhcpcd receives SIGHUP immediately after acquiring the lease, which triggers the release. dhclient receives DHCPACK and binds, then immediately is prompted to DHCPRELEASE.

In both cases, the DHCP client is left in a defunct state.

With dhcpcd:
