Unbound fatal error after enabling DHCP registration

[networknotwork]

On fully working pfSense 2.5.4 install, as soon as I enable DHCP registration on the DNS Resolver config page, unbound won't start after Apply Changes. Looked at the logs and this is what I found:

Something is messing up the path to unbound.conf to / instead of /var/unbound

Unbound starts up fine from the command line with unbound-control -c /var/unbound/unbound.conf start.

EDIT: Did some more digging and that's not the problem; the /unbound.conf path is OK since unbound does chroot to /var/unbound. The problem was my custom options, include: /var/preserve/adblock/blocked_domains.conf. For some reason that include fails when DHCP registration is enabled but works otherwise.

That some reason is the chroot.
Whatever happens, unbounc can not go outside of the chroot. It 'lives' in /var/unbound/ - that is it's "/" or root.
So "/var/preserve/" is inaccessible, except if that path lives here : /var/unbound/preserve/adblock/blocked_domains.conf

DHCP registration

This functionality restarts unbound when a new lease is registered.

Right, but it only breaks when DHCP Reg is enabled! So somehow it's escaping from the chroot jail.
