Resolvconf with FreeBSD jails

FreeBSD 9 uses resolvconf tool to manage the resolv.conf file. How can I 
make it working with FreeBSD jails?

In my case I am moving my laptop between networks and every time I boot 
FreeBSD it gets assigned a different DNS server. The file 
/etc/resolv.conf gets updated but the same file in each of the jails is 
not. I need resolv.conf in each jail in order for that jail to connect 
to the external network.

I tried to make a link from resolv.conf in a jail to the same file in 
the host system, but inside jail the link doesn't work. I could copy the 
resolv.conf every time I boot FreeBSD after the DHCP obtained new DNS 
and updated resolv.conf but before ezjail starts any of the jails, but 
where I would need to put such copying?
