submitter has been refered to the ISC to determine if there his problems
are due to a bug in the script.
As a side note, `man 8 ifconfig' does not show "ifconfig -alias" as being
acceptable, but it is and does server a purpose.
Doing so is bogus if the loop-back interface was not configured.
Typically ``network_interfaces="auto"'' will return the list of
interfaces such that "lo0" is not first. Thus there are times when
`dhclient' configs an interface before "lo0" is configured.
Under BSD4.4, there's no need to add the above route, as it will be
automatically generated by the kernel.
