Currently in packstack there are some variables that are not exposed through switches in the packstack command. Particularly in
the following value is set and cannot be changed via the packstack command during provisioning.
$floating_range = '172.24.4.224/28',
Can this be changed to allow for an option during execution of packstack?
All necessary values are filled from answer file to manifest templates by packstack. The one you are pointing to is a default value in provision class and it is indeed changed according to answer file in packstack/pupppet/templates/provision.pp line 9 (floating_range => '%(CONFIG_PROVISION_DEMO_FLOATRANGE)s',)
