Storage space, /mnt/ephemeral, /home/user/.emu

I’m trying to set up to work in a repo that has multiple build systems, and I’m finding it very difficult to make this work.

First, I have noticed that some workspaces I’ve set up in IDX have a /mnt/ephemeral space. I went to smooth over my dev environment to use this for larger package fetches and build target dirs, built a new workspace using this approach - and my new workspace doesn’t have even have /mnt/ephemeral. Is there a way to get this configured into a workspace as part of the configuration?

Similarly, when looking at what I’m using space for, I see that /home/user/.emu is taking >5G. I can’t remove it, but I’m also not doing any Android dev. I configured my workspace from the empty template. It’s using over half the home directory space associated with my workspace.

I’d love other ways to temporarily store build-related content while I’m working, but fixing either/both of these issues would go a long way to making IDX usable for my use case.
