--- Comment #1 from cr...@rlwinm.de ---
As you already identified the problem is that ifconfig_<name>="... DHCP"
doesn't work inside a vnet jail.
The reason for this is that DHCP instead of SYNCDHCP relies on devd to respond
to link up events and which is impossible inside a jail since it would require
opening /dev/devctl inside the jail to get events into the kernel and that
device support only one opening at a time (like tun and tap device).
You have to use SYNCDHCP inside the jail or configure the host's devd to match
on the jail interface name(s) with a higher priority than the default rules to
make async DHCP work and use jexec to run the same script inside the correct
jail with jexec.
