>From an apparmor pov those 2 kernels are almost identical, with the 4.4 kernel picking up a couple of backport patches, that just do some simple remapping and should not affect behavior.
There are however some external changes that could affect apparmor mediation binfmt_elf change (9f834ec18defc369d73ccf9e87a2790bfa05bf46) - that could very well be related to the name="overlay/etc/ld.so.cache" failure there are several changes in overlayfs that may result in permission changes. We can build som test kernels, a 4.4 kernel with the binfmt_elf commit cherry-picked and another one with the newer overlayfs. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701297 Title: NTP reload failure (unable to read library) on overlayfs Status in cloud-init: Incomplete Status in apparmor package in Ubuntu: Confirmed Status in cloud-init package in Ubuntu: Incomplete Status in linux package in Ubuntu: Confirmed Bug description: After update [1] of cloud-init in Ubuntu (which landed in xenial- updates on 2017-06-27), it is causing NTP reload failures. https://launchpad.net/ubuntu/+source/cloud-init/0.7.9-153-g16a7302f- 0ubuntu1~16.04.1 In MAAS scenarios, this is causing the machine to fail to deploy.
