Never was a more contradictory sentence uttered ;-)

I like it.

Very nice!  Please take a look at tools/kwboot.c.  It is the current
in-tree tool doing the job you have set out.  However, it doesn't have
as many features as your code appears to have.

Could you lay out your patches to add missing features to kwboot?  It
would facilitate review, and would avoid duplicate tools in the source
tree.

thx,

Jason.
