Yes, which is in line with --innodb if the mysql server is not compiled
with innodb
eg.
mysqld --innodb &
ok, accepts the switch
and
mysql> show variables like 'have_inn%';

I'm not saying I agree with the behavior. I'm saying that the topic has
a wider scope than --ndbcluster. You are suggesting:
--innodb
--bdb
--ndbcluster
--isam
and some more switches I guess...
should all give warnings/errors if they are supplied and the support is
compiled in, today they don't.
I will look into why this is done this way.
