Use same algorithm as in libblkid from util-linux v2.30. 1. Take first 16 bytes from UTF-8 encoded string of VolumeSetIdentifier 2. If all bytes are hexadecimal digits, convert to lowercase and use as UUID 3. If first 8 bytes are not all hexadecimal digits, convert those 8 bytes to their hexadecimal representation, resulting in 16 bytes for UUID 4. Otherwise, compose UUID from two parts: 1. part: converted first 8 bytes (which are hexadecimal digits) to lowercase 2. part: encoded following 4 bytes to their hexadecimal representation (16 bytes) So UUID would always have 16 hexadecimal digits in lowercase variant. According to UDF specification, first 16 Unicode characters of VolumeSetIdentifier should be unique value and first 8 should be hexadecimal characters. In most cases all 16 characters are hexadecimal, but e.g. MS Windows format.exe set only first 8 as hexadecimal and remaining as fixed (non-unique) which violates specification. |

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
