Yes, if you do that, and then intergrate radns in rtsol it should be no 
problem.

But I'm not sure why you would want a user land rtsol. 

One thing I noticed when I accidentally plugged a Debian system into an
ethernet port with the wrong vlan, is that the Linux kernel picks up new
prefixes without invalidating the ones that belong to the old link.

I see in the FreeBSD man page for rtsol that it sends out new router
solications when the link status changes. (I don't know if old prefixes are
also flushed).

So I'm wondering how smart it is to have part of this processing in user space.

My person reason for putting it in the kernel is to start DUD as soon as
possible.
