Support for Proxmox

[dagmoller]

Plase add support to proxmox...

[vKnmnn]

made proxmox.d with this content: generic.cfg

for isofile in $isopath/proxmox-ve*.iso; do
  if [ -e "$isofile" ]; then
    regexp --set=isoname "$isopath/(.*)" "$isofile"
    submenu "$isoname (loopback.cfg) ->" "$isofile" {
      iso_path="$2"
      export iso_path
      search --set=root --file "$iso_path"
      loopback loop "$iso_path"
      root=(loop)
      configfile /boot/grub/grub.cfg
      loopback --delete loop
    }
  fi
done

successfully boots the grub-menu of the iso, but installation fails, when /dev/sr0 or /cdrom are being mounted, which is probably the same problem as in #124 .

tested with proxmox 4.4 and 5.1

Since Proxmox is based on Debian Stable, definitely the same issue applies to its installation process.
