Ad esempio, in NixOS viene utilizzato un unico file di configurazione del sistema (configuration.nix), \u00e8 possibile effettuare rapidamente il rollback degli aggiornamenti, \u00e8 supportato il passaggio tra diversi stati del sistema, gli utenti possono installare pacchetti personalizzati (il pacchetto viene installato nella home directory), \u00e8 possibile installare pi\u00f9 versioni dello stesso programma contemporaneamente e sono garantiti build riproducibili. La dimensione dell'immagine di installazione completa con KDE \u00e8 di 1,4 GB, GNOME \u2014 1,8 GB, e la versione console ridotta \u2014 660 MB.     <\/p>\n<p>Novit\u00e0 principali:  <\/p>\n<ul>\n<li class=\"l\"> Aggiunti 12985 pacchetti, rimossi 14109 pacchetti e aggiornati 16768 pacchetti.

Il kernel di base Linux \u00e8 stato aggiornato dalla versione 5.4 alla 5.10, e come opzione \u00e8 stato offerto il kernel 5.12.    <\/li>\n<li class=\"l\"> I desktop sono stati aggiornati a KDE 5.21.3 (+ KDE Applications 20.12.3), GNOME 3.40 e Cinnamon 4.8.1.\n<li class=\"l\"> Aggiunti nuovi servizi con GNURadio 3.8, <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/server\/dts-prohoster\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3012\">server<\/a> autenticazione Keycloak e piattaforma di discussione Discourse.      <\/ul>\n<p>Con Nix, i pacchetti vengono installati in un'apposita struttura di directory \nix\/store o in una sotto-directory nella cartella utente.

I pacchetti sono presentati come contenitori che includono i componenti necessari per il funzionamento delle applicazioni. Un approccio simile \u00e8 utilizzato nel gestore di pacchetti GNU Guix, che si basa sui principi di Nix.      <\/p>\n<p>\u00c8 possibile definire dipendenze tra i pacchetti; per la ricerca di dipendenze gi\u00e0 installate si utilizza la scansione degli hash identificativi nella directory dei pacchetti installati. \u00c8 possibile sia scaricare pacchetti binari gi\u00e0 pronti dal repository (quando si installano aggiornamenti, vengono scaricati solo i delta delle modifiche), sia compilare dai sorgenti con tutte le dipendenze.
