Lennart Poettering pakkus v\u00e4lja muudatused s\u00fcsteemihalduris systemd, mis v\u00f5imaldavad s\u00fcsteemi laadimist, kasutades juureruumi pilti, saadud v\u00e4lisest hostist HTTP-protokolli kaudu. Muudatus seisneb systemd laiendamises v\u00f5imalusega mitte ainult alla laadida ketaspilt HTTP kaudu laadimise algstaadiumis, vaid ka dekompressida alla laaditud pilti, siduda see plokkseadmest loopback-re\u017eiimis, monteerida plokkseade kui \/sysroot ja laadida sellest s\u00fcsteemi. <\/p>\n

Toetust ketaspiltide allalaadimiseks s\u00fcsteemi laadimise ajal systemd-import-generatori kaudu on juba kaasatud systemd 257 versioonis. \u00dclej\u00e4\u00e4nud funktsionaalsus on hetkel t\u00f6\u00f6tavas protot\u00fc\u00fcbis, mis vajab t\u00e4iendavat arendust. Rakenduses ei ole veel t\u00e4ielikku laadimisprotsessi toetust, kuid tulevikus plaanitakse funktsionaalsust viia nii kaugele, et toetada UEFI HTTP Booti kaudu universaalseid tuumapilte UKI (Unified Kernel Image), mis \u00fchendavad \u00fches failis UEFI laaduri (UEFI boot stub), Linuxi tuumapildi ja laaditava s\u00fcsteemikeskkonna initrd. <\/p>\n

S\u00fcsteemipildi allalaadimise URL-i kavandatakse arvutada EFI-pildi jaoks UEFI HTTP Boot seadetes m\u00e4\u00e4ratud URL-i alusel (n\u00e4iteks kui EFI HTTP Booti kaudu laaditakse «http:\/\/example.com\/somedir\/myimage.efi», siis UKI initrd-protsessor laadib rootfs pildi kui «http:\/\/example.com\/somedir\/myimage.raw.xz»). Edasi plaanitakse HTTP t\u00e4iendusena lisada tugi NVMe-over-TCP tehnoloogiale, mis v\u00f5imaldab v\u00f5rgu kaudu p\u00f6\u00f6rduda NVMe-m\u00e4lude poole (NVM Express over Fabrics), kasutades TCP protokolli. <\/p>\n

Eeldatakse, et v\u00e4lisest hostist saadud piltide laadimine lihtsustab kaasaegsete muutumatute («immutable») operatsioonis\u00fcsteemide testimise korraldamist reaalses riistvaras. Arendaja saab oma arvutis luua pildi s\u00fcsteemikeskkonnaga t\u00f6\u00f6riista mkosi abil ja teha selle HTTP kaudu k\u00e4ttesaadavaks k\u00e4suga «mkosi -f serve». Arvutis, kus on vaja s\u00fcsteemi t\u00f6\u00f6d testida, piisab EFI HTTP kaudu laadimise lubamisest ja allalaadimise URL-i lisamisest k\u00e4suga: kernel-bootcfg —add-uri=http:\/\/192.168.47.11:8081\/image.efi —title=testloop —boot-order=0 <\/p>\n

Seej\u00e4rele saab lihtsalt arvuti taask\u00e4ivitada ja see laadib UKI tuuma t\u00fc\u00fcpilise pildi, mis seej\u00e4rel laadib arendaja ettevalmistatud ketta pildi koos juurte FS-iga. Enne EFI laadimise keelamist HTTP kaudu, iga j\u00e4rgmine arvuti taask\u00e4ivitamine toob kaasa v\u00e4rske s\u00fcsteemi pildi laadimise. Sellise testimise k\u00e4igus ei m\u00f5juta kohalikud kettad.
