To somewhat answer my own question, when babel is used on a standalone
"AP" interface, it is unable to automagically determine the channel it
is on. So I guess whatever it uses can only figure out a adhoc
interface? I imagine it would have grave difficulty on bridged
devices.... (in my case I am anticipating having several p2p links
over conventional AP wifi)

The log fills with:

Couldn't determine channel of interface wlan0: Invalid argument.
Couldn't determine channel of interface wlan1: Invalid argument.

For more info on my first build and test in many months, see:

https://lists.bufferbloat.net/pipermail/cerowrt-devel/2015-June/004695.html

Still, diversity more on by default strikes me as a goodness. Moving
to manually configure now.

...

Secondly, having babel logging *on* by default in the std openwrt
build strikes me as a bad idea for reasons like this:

Better for a user to expressly enable logging in openwrt if needed.
