Lennart Poettering a propus s\u0103 includ\u0103 \u00een managerul de sistem systemd o modificare care permite \u00eenc\u0103rcarea sistemului folosind o imagine a sistemului de fi\u0219iere r\u0103d\u0103cin\u0103 ob\u021binut\u0103 de la un gazd\u0103 extern\u0103 prin protocolul HTTP. Modificarea const\u0103 \u00een extinderea capabilit\u0103\u021bilor systemd de a desc\u0103rca nu doar imaginea discului prin HTTP \u00een stadiul ini\u021bial de \u00eenc\u0103rcare, ci \u0219i de a decomprima imaginea desc\u0103rcat\u0103, a o lega de un dispozitiv de bloc \u00een modul loopback, a monta dispozitivul de bloc ca \/sysroot \u0219i a \u00eenc\u0103rca sistemul de pe acesta. <\/p>\n

Support for downloading disk images during system boot via systemd-import-generator is already included in systemd 257. The rest of the functionality is still in the prototype stage, requiring further development. Currently, the full boot cycle is not supported, but in the future, the functionality is planned to be enhanced for booting via UEFI HTTP Boot of universal kernel images UKI (Unified Kernel Image), which combines in a single file the boot loader for UEFI (UEFI boot stub), the Linux kernel image, and the initial system environment initrd loaded into memory. <\/p>\n

URL-ul pentru desc\u0103rcarea imaginii sistemului va fi calculat pe baza URL-ului specificat pentru imaginea EFI \u00een set\u0103rile UEFI HTTP Boot (de exemplu, atunci c\u00e2nd se porne\u0219te prin EFI HTTP Boot «http:\/\/example.com\/somedir\/myimage.efi», handlerul UKI initrd va desc\u0103rca imaginea rootfs ca «http:\/\/example.com\/somedir\/myimage.raw.xz»). Ulterior, pe l\u00e2ng\u0103 HTTP, se inten\u021bioneaz\u0103 ad\u0103ugarea suportului pentru tehnologia NVMe-over-TCP, care permite accesarea unit\u0103\u021bilor NVMe prin re\u021bea (NVM Express over Fabrics), folosind protocolul TCP. <\/p>\n

Se estimeaz\u0103 c\u0103 \u00eenc\u0103rcarea din imagini ob\u021binute de la un gazd\u0103 extern\u0103 va simplifica organizarea test\u0103rii sistemelor de operare moderne, inalterabile («immutable») pe echipament real. Dezvoltatorul poate crea pe computerul s\u0103u o imagine cu mediu sistem folosind utilitarul mkosi \u0219i o poate face disponibil\u0103 prin HTTP cu comanda «mkosi -f serve». Pe computerul pe care se dore\u0219te testarea func\u021bion\u0103rii sistemului, este suficient s\u0103 se activeze \u00een EFI pornirea prin HTTP \u0219i s\u0103 se adauge URL-ul imaginii care se va \u00eenc\u0103rca cu comanda: kernel-bootcfg \u2014add-uri=http:\/\/192.168.47.11:8081\/image.efi \u2014title=testloop \u2014boot-order=0 <\/p>\n

Dup\u0103 care se poate pur \u0219i simplu reporni calculatorul \u0219i acesta va \u00eenc\u0103rca imaginea standard a nucleului UKI, care va \u00eenc\u0103rca apoi imaginea de disc preg\u0103tit\u0103 de dezvoltator cu sistemul de fi\u0219iere r\u0103d\u0103cin\u0103. P\u00e2n\u0103 la dezactivarea \u00eenc\u0103rc\u0103rii EFI prin HTTP, fiecare repornire ulterioar\u0103 a computerului va duce la \u00eenc\u0103rcarea unei imagini de sistem proaspete. \u00cen timpul acestui test, discurile locale nu sunt afectate.
