Thank you for your answer, I didn't know about the "new image mechanism".

I see it depends on an external 'genimage' tool. I am a bit nervous
about switching at this stage. What I ended up doing is creating a
local  rules/post/image_ubi.make file in my BSP. This just redefines
the $(IMAGEDIR)/root.ubi target so that instead of using the default
ubi.ini file from ptxdist, it will use a custom ubi.ini file.

I assume that I can override a .make file in rules/post just I would
override a .make file in rules/. I have confirmed that this works -- I
just want to make sure it is not working just out of luck :-)

Do you see any obvious problems with this approach?

Thank you.
