Ubuntu Touch installation guide

[User 16030]

Right now, the wiki page states that installation to eMMC requires a magic script yet to be written.

Is anybody working on writing said magic script?

I put those words in the wiki as a provocative placeholder  
I am 99.9% certain plain old dd will work, but figure I want to try it before I write it!
Equally with a couple of the probable releases already having install scripts (e.g. postmarketOS) direct to SDcard  I expect  someone will do a  script modification to install direct to eMMC (and skip the intermediate SDcard). But again until it happens there is nothing to write about.

Do you happen to know how the eMMC will be presented? Does one boot the image from the SD card and then run dd from the phone? Or is there a way to mount the device as mass storage on a computer and run dd from there?

Would there be a single partition to write the image to? Because I'm a bit worried to - for instance - overwrite U-Boot or something similar.
