Adding your own custom operating systems to the menu
(for advanced users)
You can add your own extra operating systems to the menu. However this requires that you convert your file system image to SquashFS format first.
Most Raspberry Pi operating system p_w_picpath are disk p_w_picpath containing two partitions. A FAT partition with the boot loader and kernel files, and a second ext4 partition with everything else. We are interested in the second partition.
With a regular Linux desktop computer that has kpartx and mksquashfs installed, you can convert the second partition to SquashFS like this:
$ sudo kpartx -av image_you_want_to_convert.img
add map loop0p1 (252:5): 0 117187 linear /dev/loop0 1
add map loop0p2 (252:6): 0 3493888 linear /dev/loop0 118784
$ sudo mount /dev/mapper/loop0p2 /mnt
$ sudo mksquashfs /mnt converted_image.squash -comp lzo -e lib/modules
$ sudo umount /mnt
$ sudo kpartx -d image_you_want_to_convert.img
(We are excluding /lib/modules from the image, because the kernel modules shipped with berryboot are used instead, and shared with all distributions.)
Put your SquashFS formatted image on a USB stick, go to the “Operating system installer”, hold down your mouse button over “Add OS” and select “Install from USB stick.
If your image prefers to have a certain memory split use the extension .img128 .img192 or .img224 instead of .img. |
