    Just to make sure that there's not too much confusion on wtmp vs wtmpx
    and utmp vs utmpx, this is how it works;
    
            wtmp - old SYSV style wtmp files (see utmp.h), keeps record
                   of all log in/log outs
            wtmpx - eXtended version of wtmp: adds hostname and extends other
                    records (32 char user vs 8 char user, 32 bit pid vs 16 bit
                    pid)  See utmpx.h
    
    wtmp and wtmpx record the same information in parallel (the routines
    that update them update both)  wtmp if for backward compatibility.
    
    Wtmp will go away.
