Sylvain,

The above looks useful, but, at first glance, is missing *a lot* of
quoting.  I'd say that at least all variable expansions (${VAR}) have to
be double-quoted.  I would also use a pipe instead of /etc/passwd-bak-tmp
in the last mkpasswd/sed chain, but that's pretty minor.
I'll take a better look later, if I have time.
	Igor
