Comment 24 for bug 1629540

Looking at the 'bugged' output :
...
error: Failed to run: ip -6 addr add dev lxdbr0 fd88:b7ac:afb7:4c42::1/64:
RTNETLINK answers: Permission denied
...

Though, we may look at the 'ip' source code for the real explanation of the message. This is not a 'address already in use' but a permission problem...

It's hard to trace in the source code, since the message is being issued in an infinite loop of a"message receiver" function (rtnl_talk() from libnetlink.c). This chained calls seems to follow :

genl_init_handle()->genl_resolve_family()->rtn_talk()

but I'm stuck at this level. This "permission denied" seems rather strange...
