Allow unique cache directory per VM

[josh-burton]

Is your feature request related to a problem?

#111 added support for a host cache directory mounted in the VM. Currently this directory is the same for every VM.

I'm running 2 VM's on the one machine, and this is causing issues when both are attempting to use and modify the cache.

What solution would you like?

• An option to change the cache path
• An option to change the cache path per VM
• OR some unique suffix added to the cache path for each VM

What alternatives have you considered?

.

Any additional context?

Hello @josh-burton, I'm not a contributer to this project (yet 🤔 ) but I think this part from the wiki can help you out:

Tartelet exposes some environment variables that are available to the scripts being run. Refer to the table below for the environment variables exposed by Tartelet and at which point in the lifecycle they are available.

Environment Variable	Lifecycle Events	Description
RUNNER_NAME	Post-boot	The name of the runner.

https://github.com/shapehq/tartelet/wiki/Executing-Scripts

I'm thinking that maybe the -1 and -2 suffixes are available in that RUNNER_NAME variable which could help you write to a folder scoped per VM?
