Reviewing DM-1338
Ok for `-ne` instead of `-neq`, thanks.

For the second point, I agree with you that most of these checks won't be useful when Qserv and it's packaging will be quite stable, but while working on init.d script, I've observed that if some configuration variables were not correct, then the init.d fails with some unclear message or no message at all. That's why I left strong check for now, in order to ease development and debugging.

If you still want that I remove some control, could you please give me a (simple) rule for choosing if a check should be kept or removed?
