log.Warn(`You are running Geth in --dev mode. Please note the following:

1. This mode is only intended for fast, iterative development without assumptions on
security or persistence.
2. The database is created in memory unless specified otherwise. Therefore, shutting down
your computer or losing power will wipe your entire block data and chain state for
your dev environment.
3. A random, pre-allocated developer account will be available and unlocked as
eth.coinbase, which can be used for testing. The random dev account is temporary,
stored on a ramdisk, and will be lost if your machine is restarted.
4. Mining is enabled by default. However, the client will only seal blocks if transactions
are pending in the mempool. The miner's minimum accepted gas price is 1.
5. Networking is disabled; there is no listen-address, the maximum number of peers is set
to 0, and discovery is disabled.
