The funny thing is that I had been working with olsrd2 for more than a
year before the problem came up that atomic overwriting of IPv6 routes
wasn't working for older kernels.

The only thing I know (at the moment) is "debian Wheezy: BAD" and
"Ubuntu 14.10: GOOD".

IPv4 atomic overwriting has been working forever... at least 5-8
years. Maybe even during Kernel 2.4 times.
