   |  Don't we have a notion of mountcritical which could work for NFS case?
 
 Those (mountcritlocal and mountcritremote) make sure that the mounts happen
 before they are required to be used elsewhere, they have nothing to do with
 delaying mount attempts until the network is ready.
 
   |  I'm unsure what is the reason for ntp/ntpdate to be so critical.
 
 Lots of things fail to work correctly if the time is not monotonically
 increasing.   Unlike ntpd, ntpdate will step the clock, forward or backward,
 as needed (which is exactly what it should do, when run before anything else
 is started, or as little else as possible.)
 
   |  That is also another thing that could be background+retry if not
   |  critical.
 
 No, it is important, and it depends upon the network being configured.
 Don't be in such a big rush to make things happen more quickly than they
 should, NetBSD already boots to a runnable state much quicker than most
 other systems, and in general there are reasons for the sequence.   Sure,
 there are things that could start in parallel (but you might not gain quite
 as much as you think doing that) but getting it all right is not as simple
 as it seems.
 
   |  (while here, a third candidate is powerd).
 
 That ons potentially could start slower (I think) but does its startup time
 really matter?  I cannot recall ever noticing any kind of delay from
 powerd starting up (there's probably more time spent writing to the console
 that it is starting, than actually starting it...)
