I noticed a special behavior in Cockpit when entering DNS entries.
If the domain part is omitted when entering the host name, an error message is (correctly) output. However, a checkmark that was not activated before is set then. (since not set by yourself, this could be overlooked after the input correction)
Steps:
In Cockpit go to System, DNS, click on “Add DNS record”.
Set a hostname without a domain part, click on “Save”.
The check mark for “Wildcard DNS record” is now set in the mask.
Not a big thing, I just noticed that.
