This looks great, i've been wanting a dev sandbox that doesn't run the risk of costing a lot if I forget to turn it off.

I had a few issues

1. manpath: can't set the locale; make sure $LC_* and $LANG are correct

suspect this is due to it inheriting locale from my local machine? easy to get around with some updates to .bashrc

2. the $SHELL environment in my sprite is `/opt/homebrew/bin/fish` I use fish on my local (mac + homebrew) machine and it seems to have inherited from my local machine, its nice to be using fish in the sprite, but seems weird that $SHELL in the sprite points to non-existent path. Slightly concerning that a local env var is being transferred to a remote machine without my explicit permission, I have some sensitive env vars locally.
