What's the intended difference between hddimg and hdddirect?

I'm confused about the intent here. The data flow in previous releases,
even jethro, seems to be somewhat confused/broken so looking at the
source code isn't really helping here.

Is one intended to be a simple syslinux bootable image while the other
is a "live" image with multiple boot choices?

In master... How does one go about requesting either a vmdk of a live
image or a directly bootable vmdk?


I'm not sure the difference between the .hddimg and .hdddirect.
I tried converting a .hddimg to .vdi or .vmdk using the VBoxManage
tool, but that didn't come up - there was a message about (paraphrased)
"waiting for removable media to become ready"  and the boot just hung up

However, I do know that .vmdk will boot easily with VirtualBox
Just add this to your local.conf
  IMAGE_FSTYPES += " vmdk"

Note: as mentioned in the documentation, you must use += as
IMAGE_FSTYPES_append will not do.
That hasn't worked for me yet on any branch I've tried.  Some build.  
None boot even past syslinux.  A variety of errors.


That's why I'm asking about intent and/or design.  If there's a plan, 
perhaps I can chip in.  But perhaps there is no concerted effort nor 
well known plan, in which case I can probably invent one if I can 
appreciate the relevant contexts.


In particular, *which* hdd should vmdk be an image of?  hddimg, (which 
builds and boots prior to master), or hdddirect, (which doesn't boot for 
me at all so I don't even know what it's intended to do)?  How do I get 
the old, single syslinux boot target hddimg, (the one that works), out 
of master?
