/etc/init.d/net.eth0-dhcp fails to terminate on shutdown (it's looking for the wrong PID file /var/run/dhcpcd-.pid) this happens using baselayout-1.7.3-r3
/etc/init.d/net.eth0-dhcp is depriciated, please use /etc/init.d/net.eth0 and have a look at the /etc/conf.d/net for info on how to use with dhcp. You will see that the latest baselayouts do not even install it anymore.
