Por ejemplo, en NixOS se utiliza un \u00fanico archivo de configuraci\u00f3n del sistema (configuration.nix), se ofrece la posibilidad de revertir actualizaciones r\u00e1pidamente, se admite el cambio entre diferentes estados del sistema, se permite la instalaci\u00f3n de paquetes individuales por usuarios (el paquete se instala en el directorio de inicio), se pueden instalar varias versiones de un mismo programa simult\u00e1neamente, y se garantizan compilaciones reproducibles.

Al habilitar Pantheon a trav\u00e9s de la configuraci\u00f3n services.xserver.desktopManager.pantheon.enable, tambi\u00e9n se activa autom\u00e1ticamente la pantalla de inicio de sesi\u00f3n relacionada.<\/p>\n<li class=\"l\"> En el instalador gr\u00e1fico, despu\u00e9s de la instalaci\u00f3n, se habilita el inicio autom\u00e1tico de la sesi\u00f3n gr\u00e1fica (anteriormente se mostraba un mensaje de consola sugiriendo ejecutar \u00absystemctl start display-manager\u00bb si se necesitaba la interfaz gr\u00e1fica). Se ha a\u00f1adido la opci\u00f3n \u00abDisable display-manager\u00bb en el men\u00fa de arranque para deshabilitar el inicio del gestor de pantalla.\n<li class=\"l\"> Para los pools de ZFS se asegura una ejecuci\u00f3n semanal de la operaci\u00f3n TRIM para los dispositivos NVME y SSD (configuraci\u00f3n services.zfs.trim.enable). Si ZFS est\u00e1 presente en la configuraci\u00f3n config.boot.initrd.supportedFilesystems o config.boot.supportedFilesystems, tambi\u00e9n se ejecutan peri\u00f3dicamente operaciones de verificaci\u00f3n (services.zfs.autoScrub.enable) y creaci\u00f3n autom\u00e1tica de instant\u00e1neas (services.zfs.autoSnapshot.enable).\n<li class=\"l\"> El c\u00f3digo nixos-option ha sido reescrito en C++ y ampliado con la opci\u00f3n \u00ab-r\u00bb para mostrar todas las configuraciones.\n<li class=\"l\"> Las configuraciones services.xserver.desktopManager.default y services.xserver.windowManager.default se han reemplazado por la opci\u00f3n universal services.xserver.displayManager.defaultSession (por ejemplo, services.xserver.displayManager.defaultSession = \u00abxfce+icewm\u00bb).\n<li class=\"l\"> Se han a\u00f1adido <noindex><a rel=\"nofollow\" href=\"https:\/\/nixos.org\/nixos\/manual\/release-notes.html#sec-release-20.03-new-services\">46 nuevos servicios<\/a><\/noindex>.\n<li class=\"l\"> Las im\u00e1genes para tarjetas SD se comprimen por defecto utilizando bzip2.\n<\/ul>\n<p>Al usar Nix, los paquetes se instalan en un \u00e1rbol de directorios separado \/nix\/store o en un subdirectorio en el directorio del usuario. Por ejemplo, el paquete se instala como \/nix\/store\/f2a4\u20268a143-firefox-75.0.0\/, donde \u00abf2a4\u2026\u00bb es un identificador \u00fanico del paquete, utilizado para el control de dependencias. Los paquetes se presentan en forma de contenedores que contienen los componentes necesarios para el funcionamiento de las aplicaciones.<br \/>\nUn enfoque similar se aplica en el gestor de paquetes GNU Guix, que se basa en los desarrollos de Nix.<\/p>\n<p>Es posible definir dependencias entre paquetes, y para buscar la existencia de dependencias ya instaladas se utiliza el escaneo de los identificadores hash en el directorio de paquetes instalados. Se permite tanto la descarga de paquetes binarios listos desde el repositorio (cuando se instalan actualizaciones a los paquetes binarios, solo se descargan los cambios delta), como la compilaci\u00f3n a partir de los c\u00f3digos fuente con todas las dependencias. La colecci\u00f3n de paquetes se presenta en un repositorio especial. <noindex><a rel=\"nofollow\" href=\"http:\/\/nixos.org\/nixpkgs\/\">Nixpkgs<\/a><\/noindex>.<\/p>\n<p><noindex><a rel=\"nofollow\"
