I guess that sounds like a good compromise.

Yes, it's one of those: I would really love to implement that one day 
list, along with a 100 other things unfortunately :/

ip-full for now, though I might one day get annoyed enough to write a 
smaller replacement but IIRC it uses "generic netlink" which is a bit 
more complicated than usual netlink.

I guess those people would need to use the SDK / buildroot then. I will 
try to bring it up with the other core-hackers at some point.

I don't think that the Linux kernel supports that (yet?).

Okay, got it though to be fair snapshot builds are in practice not 
really "upgradable" at the moment anyway due to the often times 
false-positive kernel version mismatch.


Cheers,
