Bug Description
I only seem to be able to make my dhcp server work properly by disabling apparmor.
With apparmor enabled it seems to complain that it is unable to open the leases file for append.
With apparmor either disabled completely (via linux command line in grub), or set to complain mode for /usr/sbin/dhcpd, the dhcp server appears to work fine (so far).
Observed with 2.10-0ubuntu11, and 2.10-0ubuntu12 (from the update of today). I do not know about any previous version, as this is my first attempt with xenial at setting up a dhcp server.
My system is being built fresh from the daily Ubuntu server AMD64 ISO of 2016.01.30. The hard disk is new, as the old one (12.04 server) failed.
I do not know if it is relevant, but I do notice an edit date of 2016.01.25 in /etc/apparmor.
The main problem log line:
kernel: [ 22.629981] audit: type=1400 audit(145436804
I gather I was supposed to file this under isc-dhcp instead of apparmour.
