a discussion for a follow-up maybe:

Better to assume --enable-kernel-install or --disable-kernel-install if system start isn't run from an interactive terminal?

My feeling is that that is too magical. It's simpler to have it just as it is now, with yes/no/default to interactive, and that the following sort of usage is accepted (though flags would be the recommended approach):

echo y | container system start

if kernelInstall == nil {
print("No default kernel configured.")
print("Install the recommended default kernel from [\(kernelDependency.source)]? [Y/n]: ", terminator: "")
guard let read = readLine(strippingNewline: true) else {
throw ContainerizationError(.internalError, message: "Failed to read user input")
}
guard read.lowercased() == "y" || read.count == 0 else {
print("Please use the `container system kernel set --recommended` command to configure the default kernel")
return
}
shouldInstallKernel = true
} else {
shouldInstallKernel = kernelInstall ?? false
}
guard shouldInstallKernel else {
return
}
print("Installing kernel...")
