Same here.
My only option was to make a little script that
copied the results from arp -anv to a temp file
and in case that file ! empty, then find the ip's in that
file and do an arp -d [ip] for every found entry.
After that load in the arp_entries file with -f.
I called the script empty_arp :)
I wonder if perl could be nice for some script like this?

However, it would be most nice if the arp antries could be loaded
before all other stuff happend during booting, but it didnt work
out, so therefore i send a question concerning arp during bootup :)
Bye,
