Currently, MAAS does not allow you to have a myhost.domain1 and a myhost.domain2. However, I believe only the fully qualified domain name should be required to be unique. This is breaking our decades-old production deployment model of using subdomains to clarify server info, ie “database1.team1.location1.company.com” and “database1.team2.location2.company.com.” Right now we have to put enough gibberish in the first part of the hostname during deployment to make it unique and then manually rename each server once it finishes booting, and then there is forever a discrepancy between the name of the machine in MAAS and the actual name of the machine running in production. Please allow duplicate machine names with unique domains. Thanks!
