>  - The branch should be suites/unstable.
>  - Add Origin: Devuan to d/control
>  - You need to update d/gbp.conf, in particular debian-branch, debian-tag and
>    pristine-tar. Devuan avoids using pristine-tar.
>  - Vcs-* fields in d/control should be https://git.devuan.org/devuan/iwd (where
>    the definitive source will be once it is accepted)
>  - You don't need quilt patches for changes in debian/. So you can just create
>    the initscript as debian/iwd.init.
>  - You shouldn't add the initscript control fragments to the maintscripts
>    manually, debhelper should do it (correctly) for you.
