Hmm. Does this mean you have 6in4 working correctly in your build of
cero? I'm still just doing it with a script, not netifd.

Hmm. We're back at wanting a message bus or std kernel api for dealing
with the ip rule database again... I fear that things like openvpn or
strongswan will really mess with this.

Babel head has three branches doing new stuff. In particular, the
configuration syntax is changing in some respects...

hah. I just realized that a couple of the commits in babeld head were
yours. cool. no need for me to lecture.

One thing that always bugged me about previous versions of babeld was
that it didn't chomp whitespace at the end of a line, hopefully that's
fixed somewhere in this patch series...

While I'm at it I note that robert bradley's attempt at atomic route
updates for babel appears to fail on 3.10rc3 on x86, leaving behind
routes, and or leaving behind permanently unreachable ones. Sigh.
