Prepare the downloaded Linux binary before installation.

## Preparation for Single-Instance Installation

When using the built-in installer, name the local executable `rtmn`. The installer
copies the binary that is currently being executed, so a mismatched download filename
can make the installed result confusing.

    ```ubient-docs-code
    Bashmkdir -p ~/rtmn-install
    cd ~/rtmn-install

    cp /path/to/downloaded/rtmn-linux-amd64 ./rtmn
    chmod 0755 ./rtmn
    ./rtmn --help
    ```

A valid binary should show these top-level commands:

    ```ubient-docs-code
    rtmn
    rtmn run
    rtmn install [flags]
    rtmn uninstall [-purge]
    rtmn rotate-token
    ```

## Preparation for Account-Isolated Installation

Account-isolated installation copies the binary into a path dedicated to each service
account.

Examples:

    ```ubient-docs-code
    /home/<account-a>/.rtmn-ops/rtmn-ops
    /home/<account-b>/.rtmn-app/rtmn-app
    /home/<account-c>/.rtmn-admin/rtmn-admin
    ```

Each binary must be executable by its service account.

Recommended permissions:

    ```ubient-docs-code
    directory: 0750
    binary:    0755
    owner:     service account
    group:     service account group
    ```
