Hi,

I have a similar problem. First, you need to disable pseudo before executing.
On begin of the line containing sudo cryptsetup add environment variable
definition: PSEUDO_DISABLED=1. This, however, does not solve the problem
of executing sudo. I've noticed from the recipe point of view, all files you don't own
are nobody:nogroup. This happens whether the task is in fakeroot or not.
