[-- Attachment #1: Type: text/plain, Size: 7436 bytes --]

Every time we edited a config zone_config_check_same_setting
returns that a identical config was found but this config was the config
we want to edit. So we now generate the id inside hook_new and pass the
id always to hook_parse_cmdline and to zone_config_check_same_setting.

So we cann skip this config.

Fixes: #11451
