Network dependent services

The patches needed  to make this work are available in bug 522206 but not yet in net-misc/dhcpcd-6.4.5. You could however patch it for yourself or manually edit the files (works for me), but be careful.

Services having "need net" in their init.d scripts like fetchmail would then start after dhcpcd is started.

They will be stopped when dhcpcd turns inactive and will be restarted when dhcpcd is back.
