Yes, I realize that now after studying crypt some more. By the way, the 
reason for using 'useradd' was the need for making a script to add a 
batch of users read from a file. That's afaik not easily done with 
'adduser' .

A slight clarification in the man page for useradd would be nice I 
think. Maybe also add something in the description of the -p option that 
the described method (crypt) truncates the password to eight characters?

Anyway, thanks for the clarification.
