Issue description

I have several questions about the binary files that binary.js installs when I run the serverless (sls) command, and the JavaScript files (such as sf-core.js) that the binary files appear to install under $HOME/.serverless/releases/x.y.z/.

Q.1 Under the following conditions, if I have already run the serverless (sls) command once and installed a binary file named serverless-<OS_TYPE>-<OS_CPU_ARCHITECTURE>-<SERVERLESS_BINARY_VERSION> (e.g. serverless-linux-amd64-0.0.2) locally using run.js and binary.js, is it guaranteed that it will not be overwritten the second time onwards? (I read binary.js and think the specifications are as written above, but I just want to confirm if my understanding is correct.)

• Condition 1: Always run on the same OS type and OS arch (e.g. linux-amd64)
• Condition 2: The version of the Serverless Framework is completely fixed in the frameworkVersion in serverless.yml (e.g. frameworkVersion: 4.4.18)

Q.2 What does the binary file serverless-<os.type>-<os.arch>- (e.g. serverless-linux-amd64-0.0.2) do? (I assume that this binary file reads the frameworkVersion: x.y.z specified in serverless.yml, if any, and then downloads the corresponding version of the Serverless Framework JavaScript files (such as sf-core.js) from the server you manage, and installs it under $HOME/.serverless/releases/x.y.z/. But is that correct? Does this binary file do anything else?)

Q.3 Is the source code for serverless-<os.type>-<os.arch>- available for viewing?

Q.4 Will the contents under the $HOME/.serverless/releases/x.y.z/ will be exactly the same as long as the frameworkVersion: x.y.z specified in serverless.yml does not change?)

Q.5 By default, JavaScript files (such as sf-core.js) seem to be installed in $HOME/.serverless/releases/x.y.z/, but can I change this path to a path of my choice? For example, can I change it to the same directory as binary.js as follows?

/<PATH>/<TO>/<MY_SERVERLESS_PROJECT>/node_modules/serverless
├── README.md
├── binary.js
