Creating disk image for Jari OS

To create a correct disk image for Jari OS, follow the next steps:

$ dd if=/dev/zero of=hd.img bs=1024 count=262144

This will create an empty image with 256Mb size.

$ sudo losetup /dev/loop0 hd.img

Setup a fake device.

$ sudo echo -e "n\np\n1\n1\n32\na\n1\nw\n" | sudo fdisk /dev/loop0

Create partition on this image.

$ losetup --detach /dev/loop0

Detach device.

$ sudo losetup --offset 32256 /dev/loop0 hd.img

Attach with offset to first partition.

$ sudo mke2fs /dev/loop0

Create ext2 file system.

$ mkdir tmp && sudo mount /dev/loop0 tmp

Mount to local tmp directory.

$ sudo mkdir -p tmp/boot/grub tmp/dev tmp/pipe tmp/etc tmp/tmp tmp/env tmp/lib

Create all required directories.

$ sudo cp /boot/grub/stage* tmp/boot/grub/ && sudo cp /boot/grub/e2fs_stage1_5 tmp/boot/grub/

Copy grub files.

$ sudo jed tmp/boot/grub/menu.lst

And fill it with the following content:

$ sudo umount tmp && sudo losetup --detach /dev/loop0

Umount image and detach device.
