Excellent.  Thanks for the confirmation.

Ok, good to know.  In this case, the ports on the APC PDU are configured
to have the host (short) names, which works as well (and was the only
way that I found to make it work in the older CentOS 5 version a few
years back).  This implies that hostname(1) on the nodes also returns
the short name rather than the FQDN.

I'll keep that in mind for the future as the elimination of another
restriction.
