Hi,

>          Planned Release:                    None => 2.03+

I think this bug should rather be closed.

Maybe with a hint that xorriso >= 1.4.3 now offers an -as mkisofs option
which addresses the problem

  --mbr-force-bootable
         Enforce an MBR partition with "bootable/active" flag if  options
         like  --protective-msdos-label  or --grub2-mbr are given.  These
         options normally cause the flag to be set if  there  is  an  MBR
         partition of type other than 0xee or 0xef.  If no such partition
         exists, then no bootflag  is  set,  unless  --mbr-force-bootable
         forces  creation  of a dummy partition of type 0x00 which covers
         only the first block of the ISO image.

Already testable from development snapshot downloaded after 1.1.2016:

  https://www.gnu.org/software/xorriso/xorriso-1.4.3.tar.gz

(The content of 1.4.3 tarball changes without notice.
 Do not package in binary distros without thorough testing !
 Do not point to it by upstream source oriented distros !)

The release date of xorriso-1.4.4 is not determined yet. Given some
foreseeable distractions in my life of the next weeks, it may well
last until late summer 2016.


Have a nice day :)

Thomas
