Been there, done that.
I'm pretty sure that lua parses everything up front.  And if it gets a
syntax error up front, slurmctld will use the previous version in
memory and drop a message in slurmctld.log.  I'm not sure what it does
if you restart slurmctld, it probably just ignores the lua file with
the syntax error.
