How to get root on nokia N9

I can’t consider the phone “mine” until I have root access to it. Without root, the phone is not “mine”, but “rented” from an uncle. With the corresponding rights for my uncle and their absence from me.
So, instructions for getting root on N9. Note not jailbreak, as This opportunity is officially present. Thanks Nokia.
Theory
Route is only available through the ssh server that appears after installing developer tools. He listens on localhost and gray addresses. After receiving the root, it is strongly recommended to change the password so as not to get an unpleasant surprise.
After that, we will make life a bit easier with the help of alias in the built-in shell.
Practice
We go into the settings, security, turn on the developer mode. Rebuys.
After the reboot, we go to the shell (at the very end of the list of applications, a black icon with a green inscription will appear).
Everything is in the shell except sudo. And su and login without suid. The only method is ssh.
ssh root@localhostPassword: rootme .
That would be all. But we want amenities.
Facilities
(from a user without root rights)
ssh-keygen(empty password or not - think for yourself) ssh-copy-id root@localhostecho alias root="ssh root@localhost" >~/.profileThat's it, now the root is obtained with the root command. Pay attention to the correct quotation marks in the line with echo. Quotation marks are ordinary, two apostrophes on top (no "Christmas trees" and "paws").
PS I was surprised to learn that debuts are used in N9, and updates are downloaded from downloads.maemo.nokia.com
