if you're lucky, you can just replace every occurence of 'localhost.localdomain'
in your filesystem to 'euclid.net' (and maybe the corresponding ip address as well)
it did the trick when i move my development machine into production...

#!/bin/sh
for A in `find / -type f`
do
  if ((grep "localhost\.localdomain" $A > /dev/null) && (file $A | grep "ASCII" > /dev/null))
  then
    echo $A
    sed s/localhost\.localdomain/eudlid.net/g < $A > $A.tmp2
    mv $A $A.tmp
    mv $A.tmp2 $A
  fi
done

the above script should replace every 'localhost.localdomain' in every text file
in your filesystem to 'euclid.net'...

as usual, don't forget to backup first...
