That is exactly what I ended up doing.  It just seems a little odd to me to
require that amount of manual effort when one wants to reuse the entire disk
for a fresh install.  I seem to recall that in 6.5 one could simply tell the
installer to do exactly that.

In any case, somehow I experienced the situation that, even though I had
'deleted' each of the old mount points, the CentOS-7 installer would not reuse
the original boot partition space but instead created a new one.  I am not
sure what was going on or what I did that caused this.  In the end I rebooted
from the liveCD and used the disk utility to manually remove all of the
partitions on the HDD and then re-installed from the minimal DVD.  That seems
to have returned the partition table to something I am more comfortable with.
