I have some server in a DC and want install Proxmox on it. The problem is they have no CD/DVD-ROM. In this case I use tools like UNetbootin (http://en.wikipedia.org/wiki/UNetbootin) (check http://en.wikipedia.org/wiki/List_of_tools_to_create_Live_USB_systems) to convert a normal ISO to a USB bootable installation medium. UNetbootin support over 11 Linux distribution and FreeBSD and FreeDOS, but is not support Proxmox. The problem is that Proxmox have the /dev folder with many files with a size of 0. By trying to copy this files on my USB stick (8 GB!) I get a size error. Also they are so many small files, that the procedure takes (before the abort!) over 2 hours. For Ubuntu I need only 8 minutes. Any idea how to bring Proxmox on a USB Stick?
