How to create user without creating a group with the same name as that
user?
By default, group is set to the same name as the user. This will create
group with the same name as the user (if the group didn't exist). You
can set group to an existing group, e.g. users and the setup function
will not create a new group with the same name as user. But note that
the group must already exist (if it does not, you can create it first
using Setup::Unix::Group).
