> There are several issues associated with hosts.
> * Uniquely identify a host. MAC address, IP are not sufficient. Perhaps store a file so that even if the hostname changes on the same physical machine, the rename can be auto-detected.
> * Ability to rename: requires using FK from an primary ID that is not the hostname, will require DB schema changes. When a host is readded, need to consider what happens if the OS or environment changes.
> * Properly delete a host (determine if we do hard-deletes that cascade across all of the log records, or soft-deletes so that the hosts persist but not in the cluster)
