Here's how I did it: https://github.com/ubports/installer-configs/blob/master/v1/lenok.json
This is very quick and dirty of course, but if we fetched the checksums automatically, it'd be a very viable solution!
@jgarciao Yes, definitely! Only problem to start implementing that right away would be that afaik they don't provide prebuilt images (yet?). Putting the entire build chain in the installer would be a little much, but if there was a server with images, that'd be great!
In the future we want to have an installer that's just a nice graphical wrapper about some pmbootstrap components that allows to set user info, a disk encryption password and the DE you want to use and have that written to any of the supported postmarketOS phones.
