Hi team

I just created a stock standerd container with the Proxmox downloaded ArchLinux template,

On boot, when I enter the container I get the following errors:


Code:
[root@99999 ~]# systemctl status sys-kernel-config.mount
● sys-kernel-config.mount - Kernel Configuration File System
   Loaded: loaded (/usr/lib/systemd/system/sys-kernel-config.mount; static; vendor preset: disabled)
   Active: failed (Result: exit-code) since Wed 2019-04-17 07:02:34 UTC; 23s ago
    Where: /sys/kernel/config
     What: configfs
     Docs: https://www.kernel.org/doc/Documentation/filesystems/configfs/configfs.txt
           https://www.freedesktop.org/wiki/Software/systemd/APIFileSystems

Apr 17 07:02:34 99999 mount[46]: mount: /sys/kernel/config: permission denied.
Code:
[root@99999 ~]# systemctl status sys-kernel-debug.mount 
● sys-kernel-debug.mount - Kernel Debug File System
   Loaded: loaded (/usr/lib/systemd/system/sys-kernel-debug.mount; static; vendor preset: disabled)

    Where: /sys/kernel/debug
     What: debugfs
     Docs: https://www.kernel.org/doc/Documentation/filesystems/debugfs.txt
           https://www.freedesktop.org/wiki/Software/systemd/APIFileSystems

Apr 17 07:02:34 99999 mount[44]: mount: /sys/kernel/debug: permission denied.
Can anyone know what I can do to fix this (it gives other issues when doing upgrades in pacman)

Please try to enable the `nesting` feature for containers with newer systemd (like arch)

cores: 10
hostname: 99999
memory: 5120
net0: name=eth0,bridge=vmbr0,firewall=1,hwaddr=B2:AC:AC:D1:51:48,type=veth
ostype: archlinux

you need nesting=1 and keyctl=1

but I migrated to debian to most of my containers

I added keyctl=1 and rebooted, but still getting:

Code:
mount: /sys/kernel/config: permission denied.

mount: /sys/kernel/config: permission denied.
* the configfs and debugfs are not mountable in a container - quite sure because that would break isolation.
However apart from the error-messages (which can be disabled by simply disabling/masking the corresponding mount-units) - what is not working?
I quickly setup an archlinux container and upgraded it - it works here.

For example When installing openssh I get the following

Code:
[root@99999 ~]#  pacman -S openssh

looking for conflicting packages...

Which I assume is due to the mounting potentially?

Ok - Thanks - can reproduce that error message here as well!
* seems this comes from systemd-tmpfiles --create (see https://bbs.archlinux.org/viewtopic.php?id=237221)
* during the run I get the following error in the journal:
Code:
Apr 19 11:01:17 archtest systemd-tmpfiles[222]: Failed to open file "/sys/devices/system/cpu/microcode/reload": Permission denied
which is to be expected in a container
* with some grepping - it seems that the package 'linux-firmware' ships a file which tries to access the file
* AFAIK a container does not really need the package - so removing it also removes the error-message - `pacman -R linux-firmware`

Apart from that I think that the message can be ignored as well

Hope this helps!
