Suppose this:
update_domain guerra.cr NULL NULL NULL (NULL GUERRA-CR-K NULL)
This example adds keyset GUERRA-CR-K to domain guerra.cr.
Now lets try to dissociate that keyset:
update_domain guerra.cr NULL NULL NULL (NULL () NULL)
It does not work. Notice that I don't use NULL which, in that context
does not touch the keyset entry. () should mean no keyset, right?. The
same applies to dissociating an nsset making the domain a reserved one.
For example:
update_domain guerra.cr.NULL NULL NULL (() NULL NULL)
Best regards.
