### **Prerequisites (`HOST)`**

{% hint style="info" %}

* [**Fuse**](broken://pages/8hHKbF95BBtvZUMBe4k9): Required for mounting Filesystems & Images (Can still be run with `--runtime-extract-and-run | RUNTIME_EXTRACT_AND_RUN=1` )
* [**Fonts**](broken://pages/1Jy4S9xshgEUK6bIc0fl): Required to display/render Non-English Chars, Emojis, Symbols etc.
* [<mark style="color:blue;">**Kernel User NameSpaces**</mark>](broken://pages/tjmP70tpwiHVQQutUXFd): Required for Sandboxing, Security & Performance
  {% endhint %}

***

### Sandbox

{% hint style="success" %}
RunImages have built-in sandboxing, check the docs: <https://github.com/VHSgunzo/runimage#usage>
{% endhint %}

***

### Quirks

{% hint style="info" %} <mark style="color:red;">**WARNINGS**</mark>

* NEVER run **`strip`**, **`objcopy`** or any other binary rewriting tool as they will often just strip the **`squashfs|dwarfs`** archive, only preserving the **`runtime`**.
* A typical <mark style="color:green;">**`.runimage`**</mark> file is not a real elf binary, thus will not survive this process.
