Read and correct the errror messages from named-checkconf. named.conf
and the zone's contents are not consistant. named.conf says the zones
name is "zone001" while the $ORIGIN say it is "keith1q2w.com" so not
records for "zone001" are found.
"zone001" != "keith1q2w.com"

P.S. named would have loaded if the load had been attempted. This
was named-checkconf reporting errors and the startup script choosing
to abort the startup. I would have expected this sort of error to
abort a restart before shutting down the running server but to not
stop a named starting up in the first place (i.e. on reboot).
