So far, the environment used by `command` was completely leaky and the one used by `nix` was very leaky despite it trying to be a "hermetic" environment. This commit moves the hermaticity to `command` and changes its implementation to be not leak anything. To achieve this, the following changes were also nessecary: - the `files` and `snapshot` fixture now use the folder `test-home` within the tmp_path directory by default, as the `HOME` environment variable is set to there. (extraction not possible due to dependencies of command etc also using this directory) Fixes: #847, #848 Change-Id: I55f86ee0e1615e73fcf442ee2f28f3b89893bbb4
