Okay, I have to clear up the wiki about this...

dlep_radio and olsrd2 are two applications, both based on OONF... but
you don't need both, they are just two programs using the same API.

comment out "option info all" and "option debug all" to get the
warnings... only activate info/debug either for a specific subsystem
or for when you debug a node.

see "olsrd2 --schema=log.info" or "olsrd2 --schema=log.debug" for the
possible options.

Okay, I thought I had cleaned this up, but it seems a few things
slipped when I worked on the UCI scripts.

Ahh okay, I forgot about the "ignore" option... thats something done
by the "init" script, not by olsrd2 ;)

There are also makefile targets just to compile a single thing. e.g.:

make olsrd2_static

Both "ifaddr_filter" and "routable" are Apache2-style ACLs... with a
black/whitelist of IPs/prefixes. This should make it possible to use
the same configuration for most nodes.

You are welcome.
