Pre-loading process only reads each new archive once, so it won't take time on subsequent boots (`<archive>.done` files are created to mark the read archives). If you update the archive (place a newer archive with the same name) it'll get read on the next boot as well.
Pre-loading process is `asynchronous` by default, optionally this can be set to `synchronous` through the cloud-config file or `ros config set` command. In the following example, we’ll use the cloud-config file and `ros config set` command to set RancherOS pre-loading process to `synchronous`.
_Available as of v1.4_
cloud-config file, e.g.:
```
#cloud-config
rancher:
preload_wait: true
```
`ros config set` command, e.g.:
```
$ ros config set rancher.preload_wait true
```
Pre-packing docker images is handy when you're customizing your RancherOS distribution (perhaps, building cloud VM images for your infrastructure).
