To create the read-only root filesystem, simply add the
read-only-rootfs
feature to your image.
Using either of the following statements in your
image recipe or from within the
local.conf
file found in the
Build Directory
causes the build system to create a read-only root filesystem:
IMAGE_FEATURES = "read-only-rootfs"
or
EXTRA_IMAGE_FEATURES += "read-only-rootfs"
For more information on how to use these variables, see the
"Customizing Images Using Custom IMAGE_FEATURES
and EXTRA_IMAGE_FEATURES
"
section.
For information on the variables, see
IMAGE_FEATURES
and EXTRA_IMAGE_FEATURES
.
