| # 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). |
