just tripped over INITRAMFS_TASK in kernel.bbclass, which claims to
be only for backward compatibility and should be replaced by
INITRAMFS_IMAGE:
# NOTE: setting INITRAMFS_TASK is for backward compatibility
# The preferred method is to set INITRAMFS_IMAGE, because
# this INITRAMFS_TASK has circular dependency problems
# if the initramfs requires kernel modules
but i still see usage over in
meta-openembedded/meta-initramfs/recipes-kernel/linux/linux-yocto-tiny-kexecboot_3.1[07].bb:
INITRAMFS_IMAGE = "initramfs-kexecboot-klibc-image"
INITRAMFS_TASK = "${INITRAMFS_IMAGE}:do_rootfs"
should that be updated, and INITRAMFS_TASK tossed?

Robert,
this is is an unobvious way to allow the build in one pass of:
- a standard kernel (without initramfs)
- a second kernel embedding an initramfs
The 'preferred method' does inject the initramfs in any recipe using
kernel.bbclass so to keep the old behavior (selectively add the
initramfs) we can circumvent it using INITRAMFS_TASK.
So no, please, don't toss it ;)
Cheers
Andrea

which is fine, but then it shouldn't be described as discouraged or
only for backward compatibility. and perhaps it should be listed in
the YP reference manual in the variable glossary as well.
