Earlier today (about 1 hour ago) we decide to move our DNS server from
staging to rack mounted space.  In theory, we should just turn off, move,
turn on.  However, caution told us to monitor the device -- 
SNOP (Standard Normal Operating Procedure).

As it turns out the system was configure for to addresses:

        primary         207.155.58.2    DNS advertised to the NIC
        and 
        new             207.155.58.20   alias for new primary interface.

Procedure is as follows:

        1.      Device went to normal shutdown (shutdown - h now)
        2.      The system was power down (physical removal of the 110 volt
cord)
        3.      The machine was powered back up.
        4.      The machine stalled and hung when trying to resolve the 
                ethernet interface with:

        network_interfaces="ed1 lo0"
        ifconfig_ed1="inet 207.155.58.2  netmask 255.255.255.0"
        ifconfig_ed1="inet 207.155.58.20  alias"

Comments:
        
        One might consider the ".2" interface to start first, but
        in our case it did not. Maybe I've not followed convention,
        maybe I've taken a horse to pasture when it should have been
        the cow..... 

        Needless to say I CAN reproduce this boot time issue!!

Work around

        In any case, I removed the NIC and commented out as below,
        rebooted and machine back online... ".20" disabled till 
        rewrite in place.

        network_interfaces="ed1 lo0"
        ifconfig_ed1="inet 207.155.58.2  netmask 255.255.255.0"
        #ifconfig_ed1="inet 207.155.58.20  alias"

Suggestions, comments, kudos welcome... cause the drugs no longer have any
effect...

                all my love.... jmj
