samba - May 2008 - add machine script option

i'm reading through the samba howto. section 6.2.3 (page 105) shows the add
machine script as follows:

add machine script = /usr/sbin/useradd -d /var/lib/nobody -g 100 -s
/bin/false -M %u

i have a problem with the -M option. i cannot find this option in useradd's
man page.

can i assume this example is incorrect??

what would be a correct example???

I am the author of that document.  The problem is that on some Linux 
distributions the "-M" option is replaced with "-m" - it
means to create the
home directory if it does not exist.  In fact, if I am not mistaken, the 
reference you are referring to specifically relates to this command on Red 
Hat Linux. Corrct?

FYI: In the real world I would probably NOT include the "-M" option.
