Have you tried the --hostname option of ipa-client-install? From the
help output:
--hostname=HOSTNAME
The hostname of this machine (FQDN). If specified, the
hostname will be set and the system configuration will
be updated to persist over reboot. By default a
nodename result from uname(2) is used.
This is not what the
person wants.
He wants to use short names instead of the FQDNs.
