Hi I'm Alexandria F., I'm working in a DebianCustomCD(
https://wiki.debian.org/DebianCustomCD ), 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="/"
set image="${imgpath}/${imgname}"
loopback loop $image
linux (loop)/live/vmlinuz boot=live root=/dev/loop0 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.
I'm trying to boot using these few commands:
mount -t ext4 -o rw,data=ordered /dev/sda10 /MyMountPoint
mount -t ext4 -o loop,data=ordered "/MyMountPoint/MySomeRawDisk(ex4format).img"
${rootmnt}
And these command are inside my initrd.img/scripts/init-premount/CustomScript,
but unfortunately this not works, when the boot starts of this CustomScript,
the initramfs-tools could not detect the /dev/sda10 partition, and log return
with this message:
mount -t ext4 -o loop,data=ordered "/MyMountPoint/MySomeRawDisk(ex4format).img"
${rootmnt}, No such file or directory
In other words, could not detect the /dev/sda10 for mount, and it happens too
when i try to mount a loop device like (/dev/loop0)
Here a stackoverflow reference of what im trying to do,

Note: please not confuse this with, How to boot a livecd.iso file inside a ext4
raw disk .img.
Thanks, i wait your answer...
