Build a bootable ISO9660 image. By default, the root
|
|
filesystem is directly packed as the ISO9660 filesystem,
|
|
which means the root filesystem will be read-only. It
|
|
requires ISO9660 filesystem support and CDROM support in the
|
|
kernel.
|
|
|
|
However, if BR2_TARGET_ROOTFS_INITRAMFS or
|
|
BR2_TARGET_ROOTFS_ISO9660_INITRD have been enabled, the
|
|
ISO9660 filesystem will only contain a kernel image and
|
|
optionally an external initrd image. In this case, the
|
|
filesystem being in RAM, it will be read/write. No ISO9660
|
|
or CDROM support is needed in the kernel.

Enable this option to have the root filesystem bundled as an

linked into the kernel is used) and the bootloader.
