Last year, I figured out how to use HashiCorp Vagrant to provision and manage virtual machines on a Chromebook. I used that for some lightweight tinkering and to learn a bit more about how to use Salt for configuration management in a safe and self-contained environment.

Well, I'm about to need to do a lot more Salt work, so last night I decided to refresh my Vagrant setup a bit. I switched to using some newer machine images ("boxes"), and made some tweaks to support the latest "onedir" Salt releases. Being able to quickly spin up/down a lab environment with minions running various Linux flavors is a huge help to my development process.

```
$ vagrant status
Current machine states:
salt running (libvirt) # master, ubuntu 22.04
minion01 running (libvirt) # ubuntu 22.04
minion02 running (libvirt) # ubuntu 20.04
minion03 running (libvirt) # rocky 8
minion04 running (libvirt) # rocky 9
```
To make it easier to deploy, test, break, tear down, and redeploy the environment:
* The Salt master blindly auto-accepts all minion keys.
* The minions register the roles:saltlab grain to aid in targeting.
* The master uses gitfs to pull the starter Salt content from this very Github repo.
* Additionally, the contents of `salt_content/local` get rsynced to `/srv/` when the master starts up to make it easier to write/test Salt content locally. This is a one-way rsync from host to VM (and not the other way around), so make sure to write your Salt content on the host and use `vagrant rsync` to push changes into the VM.
The full details of this setup are in my GitHub:

Okay, back to work!
