What is root password: 'root', 'linux' or something else? I tried
both, but failed. I mean, if someone tries to copy this line, he won't
be able to login.

Perhaps some howto about how to generate own root password and put it
in the script could be also useful. On the other hand it could be
included in the main documentation later.
