LGTM, have you tried to sync?

[macfarla]

Note this does not include bootnode config so you still need to configure that separately eg https://github.com/Consensys/linea-monorepo/blob/main/docs/getting-started/linea-mainnet/execution-layer-static-nodes.json

[macfarla]

LGTM, have you tried to sync?

yes, in progress

• the middle node is dev-elc-bu-nb-mainnet-fdifabio-linea for comparison
• top one dev-elc-bu-nb-hoodi-sally-linea-network-name-2 is configured manually with the genesis file + chain id + maru
• bottom one dev-elc-bu-nb-linea-sally-linea-network-name is configured with network=linea + maru, plus I added bootnodes to config file

[macfarla]

@fab-10 I think seeing it's actively syncing is sufficient - don't need to see it complete sync?

[fab-10]

@macfarla should not take too long to synchronize, are you doing a SNAP sync?

it's full sync, bonsai, with maru. dev-elc-bu-nb-linea-sally-linea-network-name

Don't think we need to see it finish syncing. Though would be nice. Snap sync shouldn't take that long though.

[fab-10]

I approve, but it will be nice if you can run a SNAP sync and ensure that the node follows the chain
