Si prevede che, rispetto a un riavvio normale, il riavvio soft ridurr\u00e0 il tempo di inattivit\u00e0 durante l'aggiornamento degli ambienti che utilizzano immagini di sistema pronte.       <\/p>\n<p>La nuova modalit\u00e0 permetter\u00e0 di terminare tutti i processi nello spazio utente, dopo di che si sostituir\u00e0 l'immagine del filesystem radice con una nuova versione e si avvier\u00e0 il processo di inizializzazione del sistema, senza riavviare il kernel. Inoltre, la conservazione dello stato del kernel attivo durante la sostituzione dell'ambiente utente dar\u00e0 la possibilit\u00e0 di implementare l'aggiornamento di alcuni servizi in modalit\u00e0 live, organizzando il trasferimento dei descrittori di file e dei socket di rete in ascolto per questi servizi dal vecchio ambiente al nuovo. In questo modo, sar\u00e0 possibile ridurre significativamente il tempo necessario per sostituire una versione del sistema con un'altra e garantire il passaggio senza interruzioni delle risorse ai servizi pi\u00f9 importanti, che continueranno a funzionare senza fermarsi.    <\/p>\n<p>L'accelerazione del riavvio \u00e8 ottenuta escludendo fasi relativamente lunghe, come l'inizializzazione dell'hardware, il funzionamento del bootloader, l'avvio del kernel, l'inizializzazione dei driver, il caricamento dei firmware e l'elaborazione dell'initrd. Per l'aggiornamento del kernel in combinazione con il riavvio dolce, si propone di utilizzare il meccanismo livepatch per introdurre correzioni nel kernel Linux in esecuzione senza un riavvio completo
