What I have so far matches the first description, but I just realized you might have meant the second one, so I thought I'd ask and potentially create more work for myself :) -- Ivaylo Markov Quality & Automation Engineer StorPool Storage https://www.storpool.com --===============8387723000431357662== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel --===============8387723000431357662==--
