====== Unprivileged CT ======

During restore from PBS following error occurs:

<code>
Error: error extracting archive - error at entry "random": failed to create device node: Operation not permitted (os error 1)
TASK ERROR: unable to restore CT 803 - command 'lxc-usernsexec -m u:0:100000:65536 -m g:0:100000:65536 -- /usr/bin/proxmox-backup-client restore '--crypt-mode=none' ct/803/2023-07-29T19:00:01Z root.pxar /var/lib/lxc/803/rootfs --allow-existing-dirs --repository backup@pbs@192.168.x.x:backup --ns company/pool' failed: exit code 255
</code>

**Reason of error:**

Unprivileged container cannot create device node.


**Not working workaround:**

Use restore command with ''ignore-unpack-errors'' argument:
<code bash>
pct restore 803 pbs-grunners:backup/ct/803/2023-07-29T19:00:01Z -storage nvm-grunners --unprivileged 1 --ignore-unpack-errors 1
</code>

According to:
  * [[https://bugzilla.proxmox.com/show_bug.cgi?id=3460|Add ignore-unpack-errors parameter to proxmox-backup-client restore]]
  * [[https://forum.proxmox.com/threads/pct-restore-lxc-container-with-pbs.90032/|Pct restore lxc container with PBS]]
it is not possible to restore unpriv CT from PBS. It needs to use another storage type for backups.

**Working workaround**

  * Restore as privileged from PBS
  * Backup to local storage 
  * Restore from local storage as ''unprivileged'' and ''ignore-unpack-errors'':
<code bash>
pct restore 803 /hddpool/vz/dump/vzdump-lxc-803-2023_08_01-09_44_49.tar.zst --storage nvm-dir --unprivileged 1 --ignore-unpack-errors 1
