This is a valuable addition. To enhance build configurations for immutable systems, perhaps we could introduce an environment variable (e.g., DISABLE_CLI_UPDATES) that allows users to opt out of and disable CLI-based updates.

Thanks for the suggestion. I'm not familiar with immutable systems, so not sure it's better to skip the update silently or raise an error when DISABLE_CLI_UPDATES is set. Currently, the latter is implemented.

I just want to duck my head in here and vote for this one. I have a ./update_goose.sh that I run all the time, but yes, this really seems like the right way for updates to happen.

I would remove the check for DISABLE_CLI_UPDATES as I think it makes sense not to need to check if the user is running an explicit goose update command.

Then good to merge. Thanks for the contribution!
