To check if things are working there should be a "Consensus: unknown" log in the geth startup logs.

Enable post-merge dev mode
c201ba1 
- Enables querying "finalized" blocks.
- Update geth.

The post merge dev mode doesn't seem very well documented.

It was added in this PR:

ethereum/go-ethereum#28463

To get a working genesis block, this workaround is needed

- geth --datadir /path/to/data --dev
- shut down geth
- geth --datadir /path/to/data dumpgenesis
