FESCo (Fedora Engineering Steering Committee), som er ansvarlig for den tekniske del af udviklingen af Fedora-distributionen, godkendte<\/a><\/noindex> tilbud om implementering projektet<\/a><\/noindex> ELN<\/a><\/noindex> (Enterprise Linux Next), som har til form\u00e5l at tilbyde et milj\u00f8 baseret p\u00e5 Fedora Rawhide-repositoriet, der kan anvendes til at teste funktionaliteten af fremtidige udgivelser af RHEL-distributionen (Red Hat Enterprise Linux). Der vil blive forberedt en ny buildroot til ELN og byggeprocessen<\/a><\/noindex> til at emulere opbygningen af Red Hat Enterprise Linux baseret p\u00e5 pakker med kildekoder fra Fedora-repositoriet. Projektet er planlagt til at blive implementeret i forbindelse med udviklingscyklussen for Fedora 33. <\/p>\n

ELN<\/a><\/noindex> vil give en infrastruktur, der muligg\u00f8r opbygning af Fedora-pakker ved hj\u00e6lp af metoder, der anvendes i CentOS og RHEL, og vil give mulighed for at pakkeleverand\u00f8rer tidligt kan opsnappe \u00e6ndringer, der potentielt kan p\u00e5virke udviklingen af RHEL. ELN vil ogs\u00e5 muligg\u00f8re kontrol af de planlagte \u00e6ndringer i betingede sektioner i spec-filerne, dvs. at bygge pakken med udl\u00f8sende betingelser, hvor variablen '%{rhel}' er sat til v\u00e6rdien '9' (variablen '%{fedora}' ELN vil returnere 'false'), hvilket simulerer en bygning for den fremtidige gren af RHEL. <\/p>\n

Det ultimative m\u00e5l er at genopbygge Fedora Rawhide-repositoriet, som om det var RHEL. I ELN planl\u00e6gges det kun at genopbygge en lille del af samlingen af Fedora-pakker, der er efterspurgt i CentOS Stream og RHEL. Succesfulde genopbygninger af ELN planl\u00e6gges at blive synkroniseret med interne RHEL-builds, ved at tilf\u00f8je yderligere \u00e6ndringer til pakkerne, som ikke er tilladt i Fedora (f.eks. tilf\u00f8jelse af varem\u00e6rker). Udviklerne vil dog bestr\u00e6be sig p\u00e5 at minimere forskellene mellem ELN og RHEL Next, ved at adskille dem p\u00e5 niveauet af betingelsesblokke i spec-filerne.<\/p>\n

En anden vigtig anvendelse af ELN vil v\u00e6re muligheden for at eksperimentere med implementeringen af nye ideer uden at p\u00e5virke de prim\u00e6re builds af Fedora. Is\u00e6r vil ELN v\u00e6re nyttig til at oprette Fedora-opbygninger, der afspejler oph\u00f8r<\/a><\/noindex> af st\u00f8tten til \u00e6ldre hardware og som standard aktivere yderligere CPU-udvidelser. For eksempel kan der parallelt oprettes en version af Fedora, hvor det i CPU-kravene kr\u00e6ves at st\u00f8tte instruktioner AVX2, hvorefter indflydelsen p\u00e5 ydeevnen fra anvendelsen af AVX2 i pakkerne kan testes, og der kan tr\u00e6ffes beslutning om at implementere \u00e6ndringen i den prim\u00e6re Fedora-distribution.
\nS\u00e5danne tests er relevante for at kontrollere Fedora-pakker under \u00e6ndrede krav til hardwarearkitekturer, som er planlagt i den kommende st\u00f8rre version af RHEL, uden at blokere den ordin\u00e6re pakke-kompilering og forberedelse af Fedora-udgivelser.<\/p>\n
