Comment 4 for bug 341817

I'm seeing the same thing in 10.04.

The problem is the profile in /etc/apparmor.d/usr.sbin.dhcpd3, which doesn't allow reading any files in /etc/bind.

Could we have a one-file exception added to this profile, please, to share a key between bind and dhcpd?
The original poster used rndc.key, but I prefer that every use of a key use a unique key, so I think a name such as ddns-key-1.key or (what I use) dhcp.key would be preferable.
