l-u-c post: https://mail.gnome.org/archives/ostree-list/2016-May/msg00000.html
FWIW if any transition scripts are written I'd be happy to have them in l-u-c upstream. I'm as yet unsure whether it's worth doing so, or pushing for dependent consumers to do a hard port. I'm doing the latter with my l-u-c consumers (gnome-continuous, my bashrc). Are there any l-u-c dependencies in the Debian archive?
