What you wanted to do
I wanted to change the param from a flag and expect a normal functionality of the nodes.
Why that wasn’t great, with examples
Let’s say I have a typo in the flag --my. The user needs to fix this by removing the DB files (which basically means having to delete the DB to fix a typo), as it is hard recorded (persisted) in the hard drive. That’s a bad experience for new users and newbies.
We should overwrite the values. I think they are recorded in badger format internally.
