interesting.  that means that a host whose primary ip addr is 10.0.0.5
may have the same hostid as lots of other hosts around the world.
good thing we can't get to those other 10.0.0.5 machines...

anyway, this is good.  it means if i can get the first non-localhost
ip address from ifconfig output, i can create my own hostid if the
hostid command on the system is borken.

thanks.
