[ale] Useradd Replacement or Upgrade

[Stephen Cristol]

If I may take this in a slightly different direction, in CentOS (and  
possibly other distributions) what is the difference between:

       /usr/sbin/useradd

       /usr/sbin/luseradd

I know they have slightly different command line options, but I have  
not found anything indicating the history or relationship of the  
pair. Is one intended to replace the other or are they meant to serve  
distinct functions?

Thanks,
S
