Re: [PATCH 3/8] apparmor: allow virt-aa-helper nameservices

Since quite a while libvirt-aa-helper triggers nss related apparmor denials like: operation="open" profile="virt-aa-helper" name="/etc/nsswitch.conf" operation="open" profile="virt-aa-helper" name="/etc/host.conf" operation="open" profile="virt-aa-helper" name="/etc/resolv.conf" operation="open" profile="virt-aa-helper" name="/etc/hosts" Rules to allow these are in Debian [1] / Ubuntu [2] since quite a while but do not seem to be specific to those distributions. There can be much more reasons than one would think to inadvertently use/trigger nameservices as can be seen in the comments in profiles/apparmor.d/abstractions/nameservice at [3]. The nameservices abstraction provides a nice and upgrade safe way to cover all of them.
