Lennart Poettering pakkus v\u00e4lja, et s\u00fcsteemihaldur systemd peaks v\u00f5imaldama s\u00fcsteemi k\u00e4ivitamist, kasutades juurefailis\u00fcsteemi pilti, mis saadakse v\u00e4lisest hostist HTTP-protokolli kaudu. Muudatus seisneb systemdi v\u00f5imaluste laiendamises mitte ainult diskipildi allalaadimiseks HTTP kaudu k\u00e4ivitamise algfaasis, vaid ka allalaaditud pildi t\u00f6\u00f6tlemiseks, \u00fchendamiseks plokkseadmest loopback-re\u017eiimis, plokkseadmest montaa\u017eiks kui \/sysroot ning s\u00fcsteemi sellelt k\u00e4ivitamiseks. <\/p>\n

Diskipiltide allalaadimise tugi s\u00fcsteemi k\u00e4ivitamise ajal systemd-import-generatori kaudu on juba kaasatud systemd 257. versiooni. \u00dclej\u00e4\u00e4nud funktsionaalsus on endiselt t\u00f6\u00f6tavas protot\u00fc\u00fcbis, mis vajab t\u00e4iustamist. T\u00e4ielik k\u00e4ivitusts\u00fckkel ei ole veel rakendustes toetatud, kuid tulevikus plaanitakse selle funktsionaalsuse viia universaalsete kernelipiltide UKI (Unified Kernel Image) kaudu UEFI HTTP Booti kaudu k\u00e4ivitamiseni, mis \u00fchendab \u00fches failis UEFI k\u00e4ivitaja (UEFI boot stub), Linuxi kernelipildi ja m\u00e4llu laaditava s\u00fcsteemi keskkonna initrd. <\/p>\n

S\u00fcsteemipildi allalaadimise URL-i plaanitakse arvutada p\u00f5hinedes URL-ile, mis on m\u00e4\u00e4ratud EFI-pildi jaoks UEFI HTTP Booti seadetes (n\u00e4iteks, kui k\u00e4ivitatakse EFI HTTP Boot «http:\/\/example.com\/somedir\/myimage.efi», olemasolev UKI initrd-t\u00f6\u00f6tleja laadib rootfs pildi kui «http:\/\/example.com\/somedir\/myimage.raw.xz»). Tulevikus plaanitakse muu hulgas HTTP k\u00f5rval toetada NVMe-over-TCP tehnoloogia, mis v\u00f5imaldab juurdep\u00e4\u00e4su NVMe-m\u00e4lupulkadele \u00fcle v\u00f5rgu (NVM Express over Fabrics), kasutades TCP protokolli. <\/p>\n

Eeldatakse, et v\u00e4lisest hostist saadud piltidelt k\u00e4ivitamine lihtsustab kaasaegsete muutumatute («immutable») operatsioonis\u00fcsteemide testimise korraldamist reaalses riistvaras. Arendaja v\u00f5ib oma arvutis luua pildi s\u00fcsteemi keskkonnast utiliidiga mkosi ja teha selle HTTP kaudu k\u00e4ttesaadavaks k\u00e4suga «mkosi -f serve». Arvutis, kus tuleb s\u00fcsteemi t\u00f6\u00f6d testida, on piisav lubada EFI kaudu HTTP k\u00e4ivitamine ja lisada laaditava pildi URL k\u00e4suga: kernel-bootcfg \u2014add-uri=http:\/\/192.168.47.11:8081\/image.efi \u2014title=testloop \u2014boot-order=0 <\/p>\n

P\u00e4rast seda saab lihtsalt arvuti taask\u00e4ivitada ja see laadib t\u00fc\u00fcpilise UKI tuuma pildi, mis seej\u00e4rel laadib arendaja ettevalmistatud kettapildi koos juurfailis\u00fcsteemiga. Enne HTTP kaudu EFI k\u00e4ivitamise v\u00e4ljal\u00fclitamist toob iga j\u00e4rgnev arvuti taask\u00e4ivitamine endaga kaasa v\u00e4rske s\u00fcsteemipildi laadimise. Sellise testimise k\u00e4igus ei m\u00f5juta kohalikke kettaid.
