ubuntu-image with local gadget snap

[David Harker]

Hi Steve,

Thanks for getting back to me. I did try using the --extra-snaps, but
I always just get an error from prepare_image saying it can't find the
snap. So in my model assertion I have:

 "gadget": "local-gadget.snap",

and then I pass:

 --extra-snaps /home/build/image/local-gadget.snap

on the command line, but I always seem to get the not found error. It
seems as though it's just ignoring the extra-snaps. I wonder if the
'not found' error is actually caused by a different problem since the
file does exist. Presumably other people must have this working?
Perhaps I'm missing some devmode flag or similar?

Thanks for your help.
