+
+Even though it is customarily used *for* booting GNU/Hurd systems, [[GRUB]],
+specifically GRUB legacy (which is still in wide-spread use, despite that
+rather depricative nickname), has never been ported to be installable when
+installed *from* GNU/Hurd systems:
+
+    # grub-install \(hd0\)
+    df: Warning: cannot read table of mounted filesystems
+    df: Warning: cannot read table of mounted filesystems
+    Could not find device for /boot: Not found or not a block device.
+
+There is a patch, [[grub-install.patch]], to fix that.
+
+
+`grub-install`, however, still fails while invoking `grub`:
+
+    # grub-install \(hd0\)
+    The file /boot/grub/stage1 not read correctly.
+
+    # grub
+    [...]
+    grub> dump (hd0,0)/boot/grub/stage1 /tmp/grub_stage1
+    
+    Error 18: Selected cylinder exceeds maximum supported by BIOS
