Re: dhcpcd vs dhclient

[Chris Ross <cross+netbsd%distal.com@localhost>]

  Yeah, I've done that before in /etc/ifconfig.xx0 files.  In this case, I was 
trying to use the automagic dhcpcd startup provided by a:

ifconfig_xx0="dhcp"

in the /etc/rc.conf.  It appeared that using a "up ; !sleep 3 ; dhcp" didn't do 
the job.  I suppose I should try with a longer sleep, just to make sure it 
doesn't work, but after the aforementioned attempt there wasn't a dhcpcd 
running at all, so I worried that such "advanced" usage of the "dhcp" builtin 
magic might not be supported.

  Thanks for your advice. I'll try a longer sleep and see how that works (or 
not).
