Added new environment variables:
|
||
|
|
|
||
|
|
- `NIX_CACHE_HOME`
|
||
|
|
- `NIX_CONFIG_HOME`
|
||
|
|
- `NIX_DATA_HOME`
|
||
|
|
- `NIX_STATE_HOME`
|
||
|
|
|
||
|
|
Each, if defined, takes precedence over the corresponding [XDG environment variable](@docroot@/command-ref/env-common.md#xdg-base-directories).
|

|
|
This provides more fine-grained control over where Nix looks for files, and allows to have a stand-alone Nix environment, which only uses files in a specific directory, and doesn't interfere with the user environment.
