Because there is some strange interaction with the ftpd and users and  
groups that I am trying to pin down.  How the user and group is  
displayed on the file system, versus how it is shown in an ftp client.

If I alter the portfile, I have to to rebuild the source every time to  
test my work, and as far as I know, MacPorts also does not remove  
users and groups.  It seems simpler and faster to me to just test this  
one issue this way, then close up with the port file changes.

Ok, understood.  Though I thought anything over 499 would show up in  
the login window, which is what I was trying to avoid.  This user and  
group I am creating is indeed a non login user.  How does MacPorts  
determine which uid/guid to use?  Is there a higher range that it  
starts with that also does not show up in the login window?

Thanks
