Currently, to register a filesystem, one has to call:
$(eval $(call ROOTFS_TARGET,blabla))
This is very unlike the package infrastructure, where the name of the
package is automatically guessed by the infra.
It turns out that we can now do that for the filesystem infra too.

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

# 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).
