First and only idea for now is:
- modify lib/db_helpers.py: reconcile_db_with_conf so that it's
passed whole ModelBuilder object (for its object_tree property
that we need to extract "name" attribute from)
- on top of this function, check cluster names match, inform the user
and refuse respective high-level operation if not
- in controllers/cluster.py, pass self.model instead of
self.model.getNodeNames() into aforementioned adjusted function
There may be more such low-hanging sanity checks possible, likely also
on reconcile_db_with_conf side.
Closing as it's a request for a minor enhancement, and luci is essentially frozen except for critical issues.
