Build urbackup-server image / build-and-push (push) Successful in 7m33s
The stock image has no libguestfs, so UrBackup disables image mounting and single files can't be restored from image backups. Add libguestfs-tools + kernel/supermin/qemu on top of uroni/urbackup-server:2.5.x, built by Gitea Actions into registry.ginnoir.com/ginnoir/urbackup-server (Portainer only pulls). Verified on valhalla: KVM-accelerated appliance, MOUNT TEST OK. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
