Comment 3 for bug 1402042

I've just pushed a change to lp:~smoser/curtin/trunk.lp1402042 that will prefer the tok '---' over the tok '--'.
So this should work with new maas or old maas.

Maas will just then have to change its behavior to always add the '---'. the one issue with this is that maas will then have to either
a.) require curtin at a certain version so that the new curtin will copy over args after '---'
b.) interrogate curtin for the version to see what curtin will look for and use '--' if it has too.

clearly 'a' seems the easiest, but we'll have to SRU the curtin fix first.
