Hai, Normaly i kick in sooner but im in bed fit by flu. :-( You have to add the bind paths to the apparmor profile, or disable apparmor in total, just dont remove it, should work also. debian wiki or ubuntu wiki shows how. But why are you using buster, imo really not safe, if you wany a 4.7 for stretch use my apt. When im better i can have a look into your problem more closely. greetz Louis..

Thanks, Dale I cannot seem to find a debian kernel that has a dependency on apparmor, can you provide a link ?

Then it is a bug, depend means it will be installed, recommend means what it says, it is recommended to install it, but you do not need to. I suppose it would be possible to disable, but assuming the systemd warning is a harbinger of things to come, it seemed best to me to figure it out now. I know systemd is not your thing, and I am inclined to agree; however, Debian sees it otherwise, leaving me to deal with it. Easier way out of this, stop using debian and use Devuan instead. I asked here because there is a wiki section devoted to the topic - https://wiki.samba.org/index.php/BIND9_DLZ_AppArmor_and_SELinux_Integration <https://wiki.samba.org/index.php/BIND9_DLZ_AppArmor_and_SELinux_Integration> Thus far, SELinux has not been forced by Debian. Regardless, since the apparmor install, I have not been able to get Bind9 to start if bind_dlz is enabled. As I said, apparmor has nothing to do with Samba, the same goes for selinux and, in my opinion, they should figure out how to work with Samba, not the other way round. The page on the wiki is supplied as a service, but Samba has no real way to know if the settings are correct, it relies on feedback from users.

Bob, I agree with everything you say and would rather not have it, but if Debian's kernel maintainers are correct in that more systemd service files will require apparmor, what other choice do I have but to learn it? I am not sure why Debian has decided to follow the systemd/apparmor path, but I guess I get to go along for the ride. If it becomes to onerous, I may have to do as you did and remove it. BTW, the apparmor file for ntp worked out of the box, no modifications on my part required.

I hope it resolves soon. I finally got a working apparmor config for bind_dlz and Samba; it's toward the bottom of this thread. As far as using Buster is concerned, I've found that most things work OK using Debian testing. So, what I do is use it at home and on other nonessential systems. This allows me to learn the things that break from an upgrade (like this one) one at a time, rather than having to figure all of them out during a full upgrade. I am forewarned and forearmed. In this case, I took an NT domain through the classic upgrade process and worked out those problems, only to be derailed by apparmor. (Unrelated to Samba, but the MySQL to MariaDB upgrade has not gone well at all, but I digress......)
