        There's no need to add each user at the end of this line, right?
The only time that I did that was connecting my own account with root, so
that I could su.  But, other than this, it isn't necessary, right?

        Hrm.  No * after "ckane:" and before ":101:100"?  All my entries
have it in my passwd and master.passwd files.  Also, what's the "::0:0:"
mean?

        Got one.  :)  Unfortunately, its missing stuff and has a couple
mistakes.  For example, it said that you type "adduser" to add a user.  Can
anyone recommend a good book on this?
