Named attack's legacy: 8.2 update fails when space is tight.

Summary:

	If you hear a report of a machine failing to take the update due to
insufficient space on /, look for /etc/core and remove it.

	This problem affects SPARC Classics because they have small disks, AND
SPARC 4's because the Root partition was small.

----

Detail:

Perhaps we need to make one more teeny little change to the update:

	rm /etc/core

to delete the carcas of named that died during the may attack on named.

Gary Dryfoos could not take the athena update.  The update complained
there was insufficient space on root.

Eventually we found:

-rw-r--r--   1 root     root     1149196 May 17 09:29 etc/core

On hanta-yo, my Sun running 8.2, I see that I have:

-rw-r--r--   1 root     root      297228 May 17 09:24 /etc/core

Perhaps this will only screw private workstation owners who access many
sites and happened to have a big named when the cracker killed it.
