However, after a few days from a boot, the static aliases on the LAN vanish.  Since I only have very infrequent access to it I can't say for sure what happened.  The logs seem to indicate that the interface went down and then came back up.  However, some of the static aliases were gone.  This is a bit of a guess as to when it happened.  I have dhclient.conf set with entries like:

When building a computer, I normally have the installer create the DHCP 
client stuff and then I create fixed leases on the DHCP server.
