[Bug 1180516] Re: Ubuntu boot slow

[Jamie Strandboge]

Thanks for using Ubuntu and reporting a bug. While I can't confirm this, I can see the problem. /etc/apparmor.d/sbin.dhclient has the following rules:
  # NetworkManager
  ...
  /var/lib/NetworkManager/dhclient-*.conf lrw,
  /var/lib/NetworkManager/dhclient*.lease* lrw,

Note the first should be in your environment:
  /var/lib/NetworkManager/dhclient*.conf lrw,

Can you describe your setup? Is it IPv6 only? Dual-stack?

Title:
  apparmor denial for /var/lib/NetworkManager/dhclient6-eth0.conf

Status in “isc-dhcp” package in Ubuntu:
  In Progress

Bug description:
  When I boot my freshly installed Ubuntu 13.04 it takes a very long
  time and usually stalls on the message:

  May 11 15:35:16 viper-desktop kernel: [   20.465219] type=1400
  audit(1368279316.282:32): apparmor="DENIED" operation="open"
  parent=946 profile="/sbin/dhclient"
  name="/var/lib/NetworkManager/dhclient6-eth0.conf" pid=1530
  comm="dhclient" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

  This happens nearly every time. When I run 'viper at viper-desktop:~$
  grep DENIED /var/log/kern.log' I see almost an entry for every boot I
  do. After a few minutes the boot continues and I get finally to the
  desktop. Shutting down the system is also a bit tricky as it doesn't
  powerof completely and the button needs to be pressed. I tried to use
  'ACPI=off' in GRUB, or tried this:
  http://askubuntu.com/questions/287792/not-been-able-to-shut-down-13-04
  but no success. I guess this is for another bug report or online
  search again. So I don't expect anyone's feedback on this last item.
