* Takes many tar streams and converts them to a squashfs image.
|

*
|
||||
* ## Why?
|
||||
*
|
||||
* We need a way to download OCI images (composed of layers that are tarballs) to something
|
||||
* that can be accessed inside a VM. I wanted to not need to copy the image each time a VM
|
||||
* is made. So, having a local HTTP cache and having the agent inside the VM download it into
|
||||
* a temporary filesystem would copy it. This is bad for the life of an SSD, slow for an HDD,
|
||||
* and too much to save into RAM for each VM.
|
||||
*
|
||||
* Instead, we download the images before booting the VM and package the layers up into a
|
||||
* squashfs image that can be mounted inside the VM. This way, we reuse downloaded images
|
||||
* efficiently.
