#! /bin/bash

# Some proxmox-backup-client commands such as "catalog dump" don't work with
# /tmp on reiserfs.  See https://bugzilla.proxmox.com/show_bug.cgi?id=3699

# This wrapper can be used as a workaround. It runs proxmox-backup-client in
# its own mount namespace with a tmpfs filesystem mounted on /tmp.
