The user installed the recommended 2.5.1 patches. When booting, rootuser.sh presented the following errors:
ifconfig bad address le0 le0 arp - revarp failed no rarp replies bad address hme0 hme0 auto-revarp failed: no rarp replies received.
System fails to resolve host IP address from /etc/host and no other RARP servers responded to the system's request for its IP address.
If dns [NOTFOUND=return] appears before files in /etc/nsswitch.conf, ifconfig complains at boot-time about bad address. In some cases this can cause the boot to fail.
