++@deffn Command uuid [UUID]
++Set the current @dfn{root device} to the device with the universally 
++unique identifier @var{UUID}, then attempt to mount it.  This is 
++equivalent to the @ref{root} command, but allows one to select a 
++filesystem by UUID rather than by device.
++
++The command recognises ext2, ext3, fat, hfs, jfs, ntfs, ocfs, reiserfs 
++and xfs filesystems.
++
++@strong{Note:} grub detects and recognises fat UUIDs in lower case 
++whereas examining /dev/disk/by-uuid on Linux will report fat UUIDs 
++in upper case.
++
++By not specifying @var{UUID}, the command will scan partitions on 
++attached devices and will display the device, partition type and 
++UUID for each recognised filesystem.

+Upstream: http://lists.gnu.org/archive/html/grub-devel/2009-09/msg00210.html
+Description: If you set root after running loopback, any attempts to open
+ files on the loopback device resolve the loopback file name relative to the
+ *new* root, not the root at the time loopback was invoked, and so the above
+ recurses until it runs out of stack. This causes problems for Wubi. I think
+ it's fairly clear that only the root that was in place when you ran
+ loopback should be relevant to the loopback file name.

++
++	* configure.ac: Check for Linux device-mapper support.
++
++	* util/hostdisk.c (device_is_mapped): New function.
++	(find_partition_start): New function, partly broken out from
++	linux_find_partition and grub_util_biosdisk_get_grub_dev but with
++	device-mapper support added.
++	(linux_find_partition): Use find_partition_start.
++	(convert_system_partition_to_system_disk): Add `st' argument.
++	Support Linux /dev/mapper/* devices if device-mapper support is
++	available; only DM-RAID devices are understood at present.
++	(find_system_device): Add `st' argument.  Pass it to
++	convert_system_partition_to_system_disk.
++	(grub_util_biosdisk_get_grub_dev): Pass stat result to
++	find_system_device and convert_system_partition_to_system_disk.  Use
++	find_partition_start.
++
++	* conf/common.rmk (grub_mkdevicemap_SOURCES): Add kern/env.c,
++	kern/err.c, kern/list.c, and kern/misc.c.
++	* util/deviceiter.c [__linux__]: Define MINOR.
++	(grub_util_iterate_devices): Add support for DM-RAID disk devices.
++	* util/mkdevicemap.c (grub_putchar): New function.
++	(grub_getkey): New function.
++	(grub_refresh): New function.
