Deweloperzy Fedora Linux og\u0142osili utworzenie grupy SIG (Special Interest Group) odpowiedzialnej za rozw\u00f3j projektu ELN (Enterprise Linux Next), kt\u00f3rego celem jest dostarczanie stale tworzonych kompilacji Red Hat Enterprise Linux na bazie repozytorium Fedora Rawhide. Proces opracowywania nowych ga\u0142\u0119zi RHEL zak\u0142ada wydzielenie odnogi z Fedory raz na trzy lata, kt\u00f3ra przez pewien czas rozwijana jest niezale\u017cnie, a\u017c do dopracowania finalnego produktu. ELN umo\u017cliwi emulowanie kompilacji Red Hat Enterprise Linux na podstawie migawki repozytorium Fedora Rawhide utworzonej w dowolnym momencie. <\/p>\n
Do tej pory po odga\u0142\u0119zieniu od Fedory przygotowanie RHEL odbywa\u0142o si\u0119 za zamkni\u0119tymi drzwiami. Za pomoc\u0105 CentOS Stream firma Red Hat zamierza uczyni\u0107 proces rozwoju RHEL bardziej otwartym i przejrzystym dla spo\u0142eczno\u015bci. ELN ma sprawi\u0107, \u017ce etap odga\u0142\u0119zienia CentOS Stream\/RHEL Next od Fedory b\u0119dzie bardziej przewidywalny dzi\u0119ki zastosowaniu metod zbli\u017conych do system\u00f3w ci\u0105g\u0142ej integracji. <\/p>\n
ELN udost\u0119pni osobny buildroot i proces kompilacji, kt\u00f3ry pozwoli przebudowa\u0107 repozytorium Fedora Rawhide tak, jak gdyby by\u0142o to RHEL. Pomy\u015blne przebudowy ELN maj\u0105 by\u0107 synchronizowane z eksperymentalnymi kompilacjami RHEL Next, z dodaniem do pakiet\u00f3w dodatkowych zmian, kt\u00f3re nie s\u0105 dopuszczalne w Fedorze (na przyk\u0142ad znak\u00f3w towarowych). Jednocze\u015bnie deweloperzy b\u0119d\u0105 d\u0105\u017cy\u0107 do minimalizowania r\u00f3\u017cnic, rozdzielaj\u0105c je na poziomie blok\u00f3w warunkowych w plikach spec. <\/p>\n
Dzi\u0119ki ELN towarzysz\u0105ce pakiety Fedora b\u0119d\u0105 mia\u0142y mo\u017cliwo\u015b\u0107 wczesnego wychwytywania i testowania zmian, kt\u00f3re mog\u0105 potencjalnie wp\u0142yn\u0105\u0107 na rozw\u00f3j RHEL. W tym przypadku b\u0119dzie mo\u017cna sprawdza\u0107 planowane zmiany warunkowych blok\u00f3w w plikach spec, tzn. budowa\u0107 pakiet z aktywacj\u0105 warunk\u00f3w z zmienn\u0105 '%{rhel}' ustawion\u0105 na warto\u015b\u0107 '9' (zmienna '%{fedora}' ELN zwr\u00f3ci 'false'), symuluj\u0105c kompilacj\u0119 pakietu dla przysz\u0142ej ga\u0142\u0119zi RHEL. <\/p>\n
ELN umo\u017cliwi tak\u017ce testowanie wdra\u017cania nowych pomys\u0142\u00f3w bez wp\u0142ywu na g\u0142\u00f3wne kompilacje Fedory. ELN mo\u017cna r\u00f3wnie\u017c wykorzysta\u0107 do sprawdzania pakiet\u00f3w Fedory przy u\u017cyciu nowych flag kompilatora, wy\u0142\u0105czaniu eksperymentalnych lub nieodpowiednich dla RHEL funkcji, zmianie wymaga\u0144 dotycz\u0105cych architektur sprz\u0119towych oraz aktywowaniu dodatkowych rozszerze\u0144 CPU. Na przyk\u0142ad bez zmiany standardowego procesu budowania pakiet\u00f3w w Fedorze mo\u017cna r\u00f3wnolegle przetestowa\u0107 kompilacj\u0119 z w\u0142\u0105czon\u0105 obs\u0142ug\u0105 instrukcji AVX2, a nast\u0119pnie oceni\u0107 wp\u0142yw AVX2 na wydajno\u015b\u0107 pakiet\u00f3w i podj\u0105\u0107 decyzj\u0119 o wdro\u017ceniu tej zmiany w g\u0142\u00f3wnej dystrybucji Fedora.
