I have some routers that connect to DSL using pppoe(4) and yes, I have the same problem with delayed startup. For me the impact is to isc_named and openvpn, but the result is similar -- a lot of logged errors, mostly due to inability to resolve names until the pppoe link comes up. A somewhat more difficult problem is that ospfd fails to start at all under these conditions (I have it listening for routes over the vpn links, and ospfd won't start if those links are down). I don't do anything at startup to address this, because the DSL is also prone to dropping at other times for other reasons. I considered using ifstated to fix it, but found it more expedient to simply use a cron job to "rcctl start ospfd" periodically, and to ignore everything else. Ignoring everything else works because most things resolve themselves when pppoe negotiation finally completes. I am very happy that things just start working once the link comes up, and that manual intervention isn't needed. A few logged errors from software that is able to resume normal function on its own is very little burden compared to some alternatives. -ken
