################################################################################

|
|
# We need to handle three cases:
|
|
#
|
|
# 1. The ISO9660 filesystem will really be the real root filesystem
|
|
# itself. This is when BR2_TARGET_ROOTFS_ISO9660_INITRD is
|
|
# disabled.
|
|
#
|
|
# 2. The ISO9660 filesystem will be a filesystem with just a kernel
|
|
# image, initrd and grub. This is when
|
|
# BR2_TARGET_ROOTFS_ISO9660_INITRD is enabled, but
|
|
# BR2_TARGET_ROOTFS_INITRAMFS is disabled.
|
|
#
|
|
# 3. The ISO9660 filesystem will be a filesystem with just a kernel
|
|
# image and grub. This is like (2), except that the initrd is
|
|
# built into the kernel image. This is when
|
|
# BR2_TARGET_ROOTFS_INITRAMFS is enabled (regardless of the value
|
|
# of BR2_TARGET_ROOTFS_ISO9660_INITRD).
