debian-7.4.0-mipsel-netinst.iso without boot sector

["Thomas Schmitt" <scdbackup@gmx.net>]

Hi,

while looking for test images with boot sectors for mips and mipsel,
i notice that
   http://cdimage.debian.org/debian-cd/7.4.0/mipsel/iso-cd/debian-7.4.0-mipsel-netinst.iso
delivers an ISO image without any boot sector.

The file
  .disk/mkisofs
inside the image does not show the option -mipsel-boot which would
be needed to generate a DEC Boot Block for MIPS Little Endian.

Is this intentional ?
If so:
- Are there problems with the boot sectors produced by xorriso ?
- Is no boot sector needed for debian arch mipsel ?
  How else is it supposed to boot the ISO ?

(libisofs once learned the mipsel boot sector layout from genisoimage,
 which has it from delo and libc. Much hearsay. No own experience.)


Have a nice day :)

Thomas
