This is a bug (I) introduced with the auto chroot feature. I'll see how to properly fix this but in the meantime, you can work around this by setting an explicit chroot location like this in /etc/unbound/unbound.conf:

 server:
    chroot: "/var/lib/unbound"

After some digging, the problem was not introduced by the auto-chroot feature but by the last Ubuntu specific upload:

unbound (1.4.22-1ubuntu2) trusty; urgency=medium

  * debian/patches/debian-changes: Removed lingering changes from 1.4.22-1
    upload.

This patch should be restored as it silences the warning about the open files limit and disable chroot by default.

@Jonathan, if you introduced this delta with Debian on purpose and want to have chroot enabled by default, I could try to adapt the auto chroot feature.

We can certainly reintroduce this - when I looked at the source package the patch had no explaination on why it was needed in its patch headers and I couldn't see why we should be diverging from what upstream releases.

I can confirm that a fresh install of 1.4.22-1ubuntu3 works well. Manually enabling the chroot feature also works, thanks Jonathan!
