@Krinkle would you mind rebasing this PR? We have since fixed the failing test that's broken here :) |

@JaKXz Thanks. Rebased now. |
By default, spawn-wrap writes temporary files to HOME. It used to be /tmp, but it changed that to HOME to support environments that have 'noexec' flags set on their tmpfs mount. Ref istanbuljs/spawn-wrap#3. The problem with this is that nyc now no longer works in environments without a (writable) home directory (e.g. the 'nobody' user on Linux). While it is fine to fallback to HOME, it should write elsewhere if that is unavailable, and ideally in a way that doesn't require every sysadmin or end-user to hardcode some environment variable in their package.json specifically for nyc or spawn-wrap. A common way to communicate this intent is with the XDG_CACHE_HOME environment variable. Fixes istanbuljs#951.
