Adding your own custom operating systems to the menu

Most Raspberry Pi operating system images are disk images 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:
