uuidfrom - selects how the local UUID is generated

In the normal case, heartbeat generates a UUID for each node in the system as a way of uniquely identifying a node - even if it should change nodenames. This UUID is typically stored in the file /var/lib/heartbeat/hb_uuid.

For certain kinds of installations (those booting from CDs or other read-only media), it is impossible for heartbeat to save a generated to disk as it normally does. In these cases, one can use the uuidfrom directive to instruct heartbeat to use the nodename as though it were a UUID, by specifying uuidfrom nodename.

All possible legal uuidfrom directives are shown below.
