# Filing a Nix issue
|
||||
|
||||
*WAIT* Are you sure you're filing your issue in the right repository?
|
||||
|
||||
We appreciate you taking the time to tell us about issues you encounter, but routing the issue to the right place will get you help sooner and save everyone time.
|
||||
|
||||
This is the Nix repository, and issues here should be about Nix the build and package management *_tool_*.
|
||||
|
||||
If you have a problem with a specific package on NixOS or when using Nix, you probably want to file an issue with _nixpkgs_, whose issue tracker is over at https://github.com/NixOS/nixpkgs/issues.
|
||||
|
||||
Examples of _Nix_ issues:
|
||||
|
||||
- Nix segfaults when I run `nix-build -A blahblah`
|
||||
- The Nix language needs a new builtin: `builtins.foobar`
|
||||
- Regression in the behavior of `nix-env` in Nix 2.0
|
||||
|
||||
Examples of _nixpkgs_ issues:
|
||||
|
||||
- glibc is b0rked on aarch64
|
||||
- chromium in NixOS doesn't support U2F but google-chrome does!
|
||||
- The OpenJDK package on macOS is missing a key component
|
||||
|
||||
Chances are if you're a newcomer to the Nix world, you'll probably want the [nixpkgs tracker](https://github.com/NixOS/nixpkgs/issues). It also gets a lot more eyeball traffic so you'll probably get a response a lot more quickly.

Nix, the purely functional package manager
|
||||
------------------------------------------
|
||||
Nix is a powerful package manager for Linux and other Unix systems that makes package
|
||||
management reliable and reproducible. Please refer to the [Nix manual](https://nixos.org/nix/manual)
|
||||
for more details.
|
||||
|
||||
Nix is a new take on package management that is fairly unique. Because of its
|
||||
purity aspects, a lot of issues found in traditional package managers don't
|
||||
appear with Nix.
|
||||
## Installation
|
||||
|
||||
To find out more about the tool, usage and installation instructions, please
|
||||
read the manual, which is available on the Nix website at
|
||||
<https://nixos.org/nix/manual>.
|
||||
On Linux and macOS the easiest way to Install Nix is to run the following shell command
|
||||
(as a user other than root):
|
||||
|
||||
## Contributing
|
||||
```
|
||||
$ curl -L https://nixos.org/nix/install | sh
|
||||
```
|
||||
|
||||
Take a look at the [Hacking Section](https://nixos.org/nix/manual/#chap-hacking)
|
||||
of the manual. It helps you to get started with building Nix from source.
|
||||
Information on additional installation methods is available on the [Nix download page](https://nixos.org/download.html).
|
||||
|
||||
## Building And Developing
|
||||
|
||||
### Building Nix
|
||||
|
||||
You can build Nix using one of the targets provided by [release.nix](./release.nix):
|
||||
|
||||
```
|
||||
$ nix-build ./release.nix -A build.aarch64-linux
|
||||
$ nix-build ./release.nix -A build.x86_64-darwin
|
||||
$ nix-build ./release.nix -A build.i686-linux
|
||||
$ nix-build ./release.nix -A build.x86_64-linux
|
||||
```
|
||||
|
||||
### Development Environment
|
||||
|
||||
You can use the provided `shell.nix` to get a working development environment:
|
||||
|
||||
```
|
||||
$ nix-shell
|
||||
$ ./bootstrap.sh
|
||||
$ ./configure
|
||||
$ make
|
||||
```
|
||||

||||

# Assumptions:
|

# - the "xART session seeds recovery utility"
|
||||
# appears to interact with xartstorageremoted
|
||||
# - `sudo xartutil --list` lists xART sessions

# and their seeds and exits 0 if successful. If
|
||||
# not, it exits 1 and prints an error such as:
|
||||
# xartutil: ERROR: No supported link to the SEP present
|
||||
# - xART sessions/seeds are present when a T2 chip is
|
||||
# (and not, otherwise)
|
||||
# - the presence of a T2 chip means a newly-created
|
||||
# volume on the primary drive will be
|
||||
# encrypted at rest
|

# - all together: `sudo xartutil --list`
