Is is possible to support to fork the data from mainnet to devnet chain?

[Daryl-L]

After talking with acceptance team, they said that if it is possible to fork the data from mainnet to devnet, it is convenient for developer to build DApps base on the data or scripts from mainnet.

It's interesting, and has been supported from another perspective in Neuron.

In Neuron, settings => data => ckb node config & storage sets the directory of the node, and allows users to download a synced ckb node from the internet to boost synchronization.

Maybe we can expose the directory of devnet node and add a check if it's initialized. If yes, start synchronization directly. Otherwise, the workflow remains the same as before

fork the data from mainnet to devnet chain

Does it mean copy transactions from mainnet to devnet? Or start ckb node from others' data with the same network?
