Lennart Poettering r\u00e4\u00e4kis s\u00fcsteemihalduri systemd ettevalmistusest pehme taask\u00e4ivituse re\u017eiimi lisamiseks («systemctl soft-reboot»), mis k\u00e4ivitab \u00fcmber ainult kasutajaruumi komponente, mitte Linuxi kernelit. Eeldatakse, et v\u00f5rreldes tavalise taask\u00e4ivitusega v\u00e4hendab pehme taask\u00e4ivitamine seisaku aega v\u00e4rskenduste ajal, kasutades valmis s\u00fcsteemipilte. <\/p>\n

Uus re\u017eiim v\u00f5imaldab l\u00f5petada k\u00f5ik kasutajaruumi protsessid, seej\u00e4rel asendada juur-FS pilt uue versiooniga ning k\u00e4ivitada s\u00fcsteemi initsialiseerimise protsess ilma k\u00e4rnita taask\u00e4ivitamata.

Taask\u00e4ivituse kiirus saavutatakse, v\u00e4listades suhteliselt pikad etapid, nagu riistvara initsialiseerimine, laadija t\u00f6\u00f6, k\u00e4rni k\u00e4ivitamine, draiverite initsialiseerimine, p\u00fcsivaramu laadimine ja initrd t\u00f6\u00f6tlemine. K\u00e4rni uuendamiseks koos pehme taask\u00e4ivitamisega soovitatakse kasutada livepatch mehhanismi, et teha muudatusi t\u00f6\u00f6tavas Linuxi k\u00e4rnis ilma t\u00e4ieliku taask\u00e4ivitamiseta ja rakenduste t\u00f6\u00f6 l\u00f5petamata.
