Benjamin Berg (Benjamin Berg<\/a><\/noindex>), en af ingeni\u00f8rerne hos Red Hat, der arbejder med udviklingen af GNOME, sammenfattede<\/a><\/noindex> resultaterne af arbejdet med at overs\u00e6tte GNOME til session management udelukkende ved hj\u00e6lp af systemd, uden brug af gnome-session processen. <\/p>\n

Systemd-logind er allerede l\u00e6nge blevet brugt til at styre login i GNOME systemd-logind<\/a><\/noindex>, som overv\u00e5ger sessionernes tilstand i brugersammenh\u00e6ng, styrer session-ID'er, h\u00e5ndterer skift mellem aktive sessioner, koordinerer multi-seat-milj\u00f8er, konfigurerer adgangspolitikker for enheder, giver midler til at lukke ned og g\u00e5r i dvalemodus osv. <\/p>\n

Samtidig forble en del af de session-relaterede funktioner i h\u00e6nderne p\u00e5 gnome-session-processen, der h\u00e5ndterede administration gennem D-Bus, opstart af display manager og GNOME-komponenter samt organisering af automatisk opstart af brugerdefinerede applikationer. Under udviklingen af GNOME 3.34 blev specifikke gnome-session-muligheder designet som unit-filer til systemd, der k\u00f8res i «systemd \u2014user», dvs. knyttet til en bestemt brugers milj\u00f8 og ikke til hele systemet. \u00c6ndringerne er allerede anvendt i Fedora 31-distributionen, hvis udgivelse forventes i slutningen af oktober.<\/p>\n

Brugen af systemd har givet mulighed for at organisere start af behandlere efter behov eller ved indtr\u00e6den af specifikke begivenheder, samt reagere mere sofistikeret p\u00e5 for tidlige procesafslutninger p\u00e5 grund af fejl og udvidet h\u00e5ndtere afh\u00e6ngigheder ved opstart af GNOME komponenter. Som f\u00f8lge heraf kan antallet af konstant k\u00f8rende processer reduceres og hukommelsesforbruget mindskes. For eksempel kan XWayland nu kun startes, n\u00e5r et applikationsprogram, der er baseret p\u00e5 X11-protokollen, fors\u00f8ges k\u00f8rt, og komponenter specifikke for bestemt hardware kun aktiveres, n\u00e5r s\u00e5danne hardware er tilg\u00e6ngelige (for eksempel vil behandlere for smartkort blive startet ved inds\u00e6ttelse af kortet og afsluttes ved udtagning). <\/p>\n

Brugeren har f\u00e5et mere fleksible v\u00e6rkt\u00f8jer til at styre opstarten af tjenester; for eksempel er det tilstr\u00e6kkeligt at udf\u00f8re «systemctl \u2014user stop gsd-media-keys.target» for at deaktivere behandleren for medietastene. I tilf\u00e6lde af problemer kan man se loggene relateret til hver behandler ved at bruge journalctl-kommandoen (f.eks. «journalctl \u2014user -u gsd-media-keys.service»), efter f\u00f8rst at have aktiveret debugging-logf\u00f8ring i servicen («Environment=G_MESSAGES_DEBUG=all»). Der er ogs\u00e5 mulighed for at k\u00f8re alle GNOME-komponenter i isolerede sandbox-milj\u00f8er, som stiller h\u00f8je krav til sikkerhed. <\/p>\n

To ease the transition, support for the old way of launching processes er planlagt<\/a><\/noindex> bevare i flere udviklingscyklusser af GNOME. Derefter vil udviklerne gennemg\u00e5 tilstanden af gnome-session og sandsynligvis (m\u00e6rket som «likely») fjerne opstartsmidlerne og vedligeholdelsen af D-Bus API. Derefter vil anvendelsen af «systemd \u2014user» blive en obligatorisk funktion, hvilket kan skabe vanskeligheder for systemer uden systemd og kr\u00e6ve forberedelse af alternative l\u00f8sninger, som det engang var tilf\u00e6ldet med systemd-logind<\/a><\/noindex>. Nevertheless, in his speech at the GUADEC 2019 conference, Benjamin Berg mentioned plans to maintain support for the old launch method for systems without systemd, but this information is inconsistent with the plans for p\u00e5 projektets side<\/a><\/noindex>. <\/p>\n
