Dear Maintainer,


After upgrading from version 4.4.3-P1-1 to 4.4.3-P1-1.1 the added
apparmor configurations block the include of files outside /etc/dhcp/,
like DDNS TSIG keys definition that are usually installed under
/etc/bind.

I can understand avoiding to read files everywhere, but the use of
TSIG keys defined by bind with is quite a common usage, that stop
working with misleading permission denied error for readable files.

This break previously working configurations, whitout a note in
the changelog.

As commented in usr.sbin.dhcpd:

  # access to bind9 keys for dynamic update
  # It's expected that users will generate one key per zone and have it
  # stored in both /etc/bind9 (for bind to access) and /etc/dhcp/ddns-keys
  # (for dhcpd to access).
  /etc/dhcp/ddns-keys/** r,

Indeed, unfortunately the NMU is missing a changelog update.
