rcorder (for 5.5 and 7.0 anyway) has ppp starting before named alright.  
However ppp is exec'd and begins connecting but is not waited for - as a 
rule fortunately, as even ADSL can take a while, and dialup takes a good 
long while - before proceeding with the boot, including named.

I suppose /etc/rc.d/ppp maybe could be hacked to wait around, up to some 
timeout anyway, or /etc/rc.d/named could be taught to timed-wait on some 
indication for such specific cases, but some rcorder dependencies seem 
hardly resolvable in the 'general case' .. I had the same issue with mpd 
on ADSL recently after a rare reboot; still pondering a tidy solution.

cheers, Ian
