This is weird. The root-cache should be preserved and reused. Unless you modify the config
(mtime). Then Mock assume 
configuration changed and rebuild the root-cache.


You may as well experiment with

# config_opts['plugin_conf']['root_cache_opts']['age_check'] =
True
# config_opts['plugin_conf']['root_cache_opts']['max_age_days'] =
15


# config_opts['plugin_conf']['yum_cache_opts']['max_age_days'] =
30
#
config_opts['plugin_conf']['yum_cache_opts']['max_metadata_age_days']
= 30
