Nice script! Would be cool if it would be part of cygwin. Btw. was the
/etc/nologin.txt your addition? I think the original nologin doesn't even do
that. At least not on Debian, where I just checked. 

Although in general I agree with Andrey. I forgot all about /bin/false. So I
am using that now. In fact I checked on my Linux box. I see that most
"no-shell" users have /bin/false in /etc/passwd (like ftp or mysql). But
others have nologin (e.g. user sshd on my machine).

Thanks,
gwodus.
