The image
class helps support creating images
in different formats.
First, the root filesystem is created from packages using
one of the rootfs*.bbclass
files (depending on the package format used) and then one or more image
files are created.
The
IMAGE_FSTYPES
variable controls the types of images to generate.
The
IMAGE_INSTALL
variable controls the list of packages to install into the
image.
For information on customizing images, see the "Customizing Images" section in the Yocto Project Development Manual. For information on how images are created, see the "Images" section elsewhere in this manual.
