Si prevede che, rispetto a un riavvio normale, il riavvio morbido ridurr\u00e0 i tempi di inattivit\u00e0 durante l'aggiornamento degli ambienti che utilizzano immagini di sistema preconfezionate.       <\/p>\n<p>La nuova modalit\u00e0 consentir\u00e0 di completare tutte le operazioni nello spazio utente, dopodich\u00e9 sar\u00e0 possibile sostituire l'immagine del file system radice con una nuova versione e avviare il processo di inizializzazione del sistema senza riavviare il kernel. Inoltre, mantenere lo stato del kernel attivo durante la sostituzione dell'ambiente utente permetter\u00e0 di aggiornare 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 a quello nuovo. In questo modo, sar\u00e0 possibile ridurre significativamente il tempo necessario per passare da una versione del sistema all'altra e garantire un trasferimento fluido delle risorse ai servizi pi\u00f9 critici, che continueranno a funzionare senza interruzioni.    <\/p>\n<p>La velocit\u00e0 di riavvio \u00e8 migliorata escludendo fasi relativamente lunghe come l'inizializzazione dell'hardware, il funzionamento del bootloader, l'avvio del kernel, l'inizializzazione dei driver, il caricamento del firmware e il processo initrd. Per aggiornare il kernel insieme a un riavvio morbido, si consiglia di utilizzare il meccanismo livepatch per apportare correzioni al kernel Linux in esecuzione senza un riavvio completo e senza interrompere il funzionamento delle applicazioni.<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=59099\">opennet.ru<\/a>
