Maybe you want to know why i need it?, this is the answer: Im working
in a custom livecd of debian, and i need save more time in the
debugging of the livecd, requires minus time and minus resources, the
replacement of the filesystem.squashfs inside a .img ext4 than replace
a iso9660 .iso file, and even sometimes the modifying of the .iso file
can damage the filesystem.


It might be worth talking to one of the Debian Live developers to see
whether they have a useful workflow to recommend. One such developer is
Jonathan Carter , but you may also consider
contacting the  mailing list.

Need help about development of your distributions.

Hello, I'm Alexandria F., I'm a software developer, i have all versions of your 
distributions of debian jessie and stretch(gnome,kde,xfce,cinnamon,lxde) 
downloaded, but im start in contact with you because i have some questions 
about debian live cd, for be specific(Jessie 8.0.0), my questions are:

1. It's posibly to boot a debian live cd from a raw disk (.img) with ext2 or 
ext3 or ext4 format with grub2, not in a iso9660 file?

example:
MySomeRawDisk(ex4format).img
 /boot
 /isolinux
 /live/filesystem.squashfs
 /vmlinuz
 / initrd.img
...

grub2 menuentry example:
menuentry "RawDiskBoot" {
set imgname="MySomeRawDisk(ex4format).img"
set imgpath="/image"
set image="${imgpath}/${imgname}"
loopback loop $image
linux (loop)/live/vmlinuz boot=live root=(loop) boot=live
initrd (loop)/live/initrd
}

2. How i can do run correctly my debian custom livecd boot from a raw disk 
MySomeRawDisk(ex4format).img, modifying the initrd.img, if is not possible boot 
a .img only with grub2.

Nota: please not confuse this with: How to boot a livecd.iso file inside a ext4 
raw disk .img.

Thanks, i wait your answer...
