Re: wait link up before route configuration

/etc/rc.d/netwait dependencies are
# PROVIDE: netwait
# REQUIRE: devd ipfw pf routing

[truncated] rcorder -p /etc/rc.d/*
/etc/rc.d/netif
/etc/rc.d/routing
/etc/rc.d/netwait

I've tested netwait. It doesn't work


If i configure routing like that:
# /etc/rc.conf.d/routing route_defaultgw="-host 203.0.113.1 -link 
-interface lagg0" route_default="-net 0.0.0.0/0 -interface lagg0 
203.0.113.1" static_routes="defaultgw default"

It works, but the routing table went from
# netstat -rn Routing tables Internet: Destination Gateway Flags Netif 
Expire default 203.0.113.1 UGS lagg0 198.51.100.1 link#10 UH lo0 
203.0.113.1 link#10 UHS lagg0 127.0.0.1 link#3 UHS lo0

to
Internet: Destination Gateway Flags Netif Expire default link#10 US 
lagg0 198.51.100.1 link#10 UH lo0 203.0.113.1 link#10 UHS lagg0 
127.0.0.1 link#3 UHS lo0

I don't know if it's good or not.
