Follow-up Comment #6, bug #32426 (project grub):
First of all:
-----8<---------
Reserved Field - The first 16 sectors of the track is reserved. The reserved
field can be used to store computer code to boot the operating system. This
makes the CD bootable. But most of the time, the reserved field is empty,
containing zeros.
-----8<---------
16 sectors is the 32768 bytes. My ubuntu core.img is 23817 bytes. So it fits
in that size.
Second:
Why not to change core.img file contents ? I don't think it's size is changed
during installation.
