Lennart Poettering a vorbit despre preg\u0103tirile pentru ad\u0103ugarea \u00een managerul de sistem systemd a modului de repornire u\u0219oar\u0103 (\"systemctl soft-reboot\"), care va reporni doar componentele spa\u021biului utilizatorului, f\u0103r\u0103 a afecta nucleul Linux. Se presupune c\u0103, \u00een compara\u021bie cu o repornire obi\u0219nuit\u0103, repornirea u\u0219oar\u0103 va reduce timpul de nefunc\u021bionare \u00een timpul actualiz\u0103rii mediilor care folosesc imagini de sistem gata configurate. <\/p>\n

Noul mod va permite \u00eencheierea tuturor proceselor din spa\u021biul utilizatorului, dup\u0103 care va \u00eenlocui imaginea sistemului de fi\u0219iere r\u0103d\u0103cin\u0103 cu o versiune nou\u0103 \u0219i va ini\u021bia procesul de ini\u021bializare a sistemului, f\u0103r\u0103 a reporni nucleul. \u00cen plus, p\u0103strarea st\u0103rii nucleului \u00een timpul \u00eenlocuirii mediului utilizatorului va permite actualizarea unora dintre servicii \u00een modul live, organiz\u00e2nd transferul descriptorilor de fi\u0219iere \u0219i socket-urilor de re\u021bea ascult\u0103toare pentru aceste servicii din vechiul mediu \u00een nou. Astfel, se va reduce semnificativ timpul necesar pentru \u00eenlocuirea unei versiuni de sistem cu alta \u0219i se va asigura transferul ne\u00eentrerupt de resurse pentru cele mai importante servicii, care vor continua s\u0103 func\u021bioneze f\u0103r\u0103 oprire. <\/p>\n

Accelerarea repornirii se realizeaz\u0103 prin excluderea etapelor relativ \u00eendelungate, cum ar fi ini\u021bializarea hardware-ului, func\u021bionarea \u00eenc\u0103rc\u0103torului, pornirea nucleului, ini\u021bializarea driverelor, \u00eenc\u0103rcarea firmware-ului \u0219i procesarea initrd. Pentru actualizarea nucleului, \u00eempreun\u0103 cu repornirea u\u0219oar\u0103, se propune utilizarea mecanismului livepatch pentru a face corec\u021bii \u00een nucleul Linux func\u021bional, f\u0103r\u0103 o repornire complet\u0103 \u0219i f\u0103r\u0103 a opri func\u021bionarea aplica\u021biilor.
