NixOS
NixOS è una distribuzione GNU/Linux indipendente che aspira a migliorare il sistema di configurazione. In NixOS, tutto il sistema operativo è costruito col package manager Nix. Nix memorizza tutt i pacchetti in isolamento dagli altri perciò non ci sono le direcotry /bin, /sbin, /lib o /usr e tutti i pacchetti sono dentro /nix/store.
Versione 22.11
Questa versione contiene (in Inglese):
- Software that uses the
cryptpassword hashing API is now using the implementation provided bylibxcryptinstead of glibc’s, which enables support for more secure algorithms.- Support for algorithms that
libxcryptdoes not consider strong are deprecated as of this release, and will be removed in NixOS 23.05. - This includes system login passwords. Given this, we strongly encourage all users to update their system passwords, as you will be unable to login if password hashes are not migrated by the time their support is removed.
- When using
users.users.<name>.hashedPasswordto configure user passwords, runmkpasswd, and use the yescrypt hash that is provided as the new value. - On the other hand, for interactively configured user passwords, simply re-set the passwords for all users with
passwd. - This release introduces warnings for the use of deprecated hash algorithms for both methods of configuring passwords. To make sure you migrated correctly, run
nixos-rebuild switch.
- When using
- Support for algorithms that
- The NixOS documentation is now generated from markdown. While docbook is still part of the documentation build process, it’s a big step towards the full migration.
aarch64-linuxis now included in thenixos-22.11andnixos-22.11-smallchannels. This means that when those channel update, bothx86_64-linuxandaarch64-linuxwill be available in the binary cache.aarch64-linuxISOs are now available on the downloads page.nsncdis now available as a replacement ofnscd.nscdis responsible for resolving hostnames, users and more in NixOS and has been a long standing source of bugs, such as sporadic network freezes.More context in this issue.
Help us test the new implementation by setting
services.nscd.enableNsncdtotrue.We plan to use
nsncdby default in NixOS 23.05.- Linode cloud images are now supported by importing
${modulesPath}/virtualisation/linode-image.nixand accessingsystem.build.linodeImageon the output. hardware.nvidiahas a new option,hardware.nvidia.open, that can be used to enable the usage of NVIDIA’s open-source kernel driver. Note that the driver’s support for GeForce and Workstation GPUs is still alpha quality, see the release announcement for more information.- The
emacspackage now makes use of native compilation which means:- Emacs packages from Nixpkgs, builtin or not, will do native compilation ahead of time so you can enjoy the benefit of native compilation without compiling them on you machine;
- Emacs packages from somewhere else, e.g.
package-install, will perform asynchronously deferred native compilation. If you do not want this, maybe to avoid CPU consumption for compilation, you can use(setq native-comp-deferred-compilation nil)to disable it while still benefiting from native compilation for packages from Nixpkgs.
