FreeBSD on Raspberry Pi 512MB (with U-Boot + ubldr)

[Ian Lepore]

Just an FYI, you can use a combination of ifconfig_foo=SYNCDHCP and
background_dhclient=YES to get the effect of launching dhclient from rc
rather than from devd, and still have it launch in background to avoid
delaying the startup.

I'm not saying that's what you should do, I still think devd is the way
to go, especially on a platform with usb keyboards and whatnot.  Just
letting folks know that freebsd's dhcp startup is more flexible than
ever these days.
