+- Naked image is for booting any existing .img file.
+- By default, this image has a variable called `NOPICKER` which is `"true"`. Use `-e NOPICKER=false` or any other string than the word `true` to enter the boot menu. This lets you use other disks instead of skipping the boot menu, e.g. recovery disk.
