[Buildroot] Using udev, non-static /dev, and ramfs (or tmpfs)

I have a buildroot system that has been working fine (thanks) using
a static /dev in a ramfs rootfs. Now I want to add a USB device and it
seems like I should let udev etc. handle it.
However udev cannot make entries in a read-only /dev.
Is there a simple recipe for mounting /dev as writable?
There are several compilcations:
Normally to mount with ramfs I'd use /dev/ram*.
How does that work with mounting /dev?
What about all the existing static /dev/entries?
I see that /etc/init.d/S10udev tries to use "/sbin/udevstart", but
I don't have that.
Would I be better off to keep things static?
