I think the way I wanted to implement it is to complex. Instead of that,
I’m adding an option “-n”. I just looked for a letter which was not used
yet. This option will get the SHELL, HOME, PASSWORD (if you don't want
to use SSH Keys) from environment variable (for example
DROPBEAR_SINGLEUSER_(HOME|PASSWORD|SHELL) ).
This way, it won't be a bloatware feature.

By the way, I had a simple question. For the moment, I downloaded the
latest dropbear tarball [1] and start a git repo with it to develop.
Is there a git/mercurial/whatever repo for Dropbear ? (The only repo I
saw was the historical CVS one).

Thank you.
