Description of Problem:
arping -- called by /etc/init.d/network through /sbin/ifup -- will be
executed before network filesystems gets mounted. Therefore /usr may be
unavailable at this time.
I suggest to move arping to /sbin
Steps to Reproduce:
1. mount /usr by NFS
error messages because arping was not found
$ rpm -q initscripts iputils
Fixed in rawhide.
