Subject: [PATCH container] Fix bug #6040 in the exclusion pattern of tar
Date: Sat,  4 Jan 2025 19:47:26 +0100
Message-ID: <20250104184726.95658-1-info@orwa.tech>

From: Orwa Diraneyya <diraneyyaorwa@gmail.com>

After this fix, users of Proxmox will be able to
use the root filesystem tarballs found publicly
(e.g. at https://cloud-images.ubuntu.com/) as LXC
container templates.

Currently, this results in a container-creation
failure due to the root folder `/dev` exclusion
pattern being ineffective.

The bugfix is also announced on the dev mailing
list (mailman.74.1735960093.441.pve-devel)
