} If you delete it then it will not be recreated.  You can truncate it by
} either copying /etc/utmp to it, or by copying /dev/null to it.

Is there perhaps any program out there ther truncates the /etc/wtmp
file to the 100 most recent entries?  

Since it is a binary file, this is no trivial task.

Thanks in advance.
