A little bug, easy to resolv, right? I remember that it was included in man of dhcpcd before.
If somebody is new to dhcpcd, he might not know dhcpcd can work with '--nodns'.
Yay for bug cross posting! Here's what I said at http://bugs.marples.name/show_bug.cgi?id=84 --nodns and friends only work when built with dhcpcd-3 compatability, so they don't get documented. Currently you disable dns by using -O dns_servers,dns_domain_name,dns_domain_search Although that will probably be made easier in the future with a new option that can skip hook scripts, maybe like this dhcpcd -C resolv.conf dhcpcd -C ntp dhcpcd -C ypbind as beta5 will have dhcpcd.sh split out a little.
Per Roy's comment, closing.
