The ubifs image filenames produced by the ubi and ubifs commands differ.

IMAGE_CMD_ubi produces an interim ubifs image
${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.ubifs ; whereas IMAGE_CMD_ubifs
produces a final ubifs image
${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.ubifs.img

This results in the undesirable behaviour then when a user specifies
IMAGE_FSTYPES contains ubifs (as opposed to ubi) they get a broken link
${DEPLOY_DIR_IMAGE}/${ROOTFS_IMAGE}-${MACHINE}.ubifs pointing to the
non-existant ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.ubifs

Fix the discrepancy by making the IMAGE_CMD_ubifs also produce the
.rootfs.ubifs target like the IMAGE_CMD_ubi does and preserve the old
.ubifs.img filename as a link for backwards compatibility.

So, wait. What's the problem here? If you do IMAGE_FSTYPES="ubifs" you get the interim image which isn't useful normally but is useful if you're doing volume management outside of the provided build targets. It's not however a valid rootfs target since it can't be used as is. I think what's missing here is just a comment to the effect that most people do not want 'ubifs' and they do want 'ubi' as we provide ubifs for advanced usages.

Please also consider this patch for inclusion into the 2011.03-maintenance
branch and into arago-oe-dev

Just as a general comment, I don't want combined requests for 2011.03-maintenance but do feel free to make the request as soon as it hits a mainline tree (and you've done the relevant testing on 2011.03-maintenance).

The reason I want to be able to address the ubifs image -- and
not the UBI image -- is because I am trying to produce a UBI image from a
a different ubinize config file which will contain both rootfs and
kernel volumes.

I am trying to accomplish this by creating a recipe which depends on the
rootfs and kernel images we use. This recipe needs to synthesize the image
file path, but without this patch it isn't simple since the link
${DEPLOY_DIR_IMAGE}/${ROOTFS_IMAGE}-${MACHINE}.ubifs is broken.

So, this is a valid use case (which I was spelling out above, before I got down here). but I think you're using the wrong variables. There should be something that maps over to ${IMAGE_NAME}.ubifs.img
