as boot_states changed we should change the default value for the node
-- nodes
----------------------------------------
ALTER TABLE nodes ADD COLUMN node_type TEXT REFERENCES node_types DEFAULT 'regular'; -- node types
+ALTER TABLE nodes ALTER COLUMN boot_state SET DEFAULT 'reinstall'; -- boot_states changed in planetlab5.sql
ALTER TABLE nodes ADD COLUMN verified boolean NOT NULL DEFAULT false; -- whether or not the node & pcu are verified
ALTER TABLE nodes ADD COLUMN run_level TEXT REFERENCES run_levels DEFAULT NULL; -- Node Run Level
