Commentant l'intention<\/a><\/noindex> les d\u00e9veloppeurs de Fedora incluent par d\u00e9faut un processus en arri\u00e8re-plan earlyoom<\/a><\/noindex> pour une r\u00e9action rapide \u00e0 la p\u00e9nurie de m\u00e9moire dans le syst\u00e8me, Lennart Poettering qu'une fois, il avait accidentellement supprim\u00e9 certains fichiers syst\u00e8me en modifiant le th\u00e8me Ubuntu Yaru. De plus, il n'avait pas de sauvegardes en raison d'une erreur dans les expressions r\u00e9guli\u00e8res. Selon ses dires, un syst\u00e8me d'exploitation immuable aurait pu \u00e9viter ces probl\u00e8mes.<\/a><\/noindex> sur les plans d'int\u00e9gration d'une autre solution dans systemd \u2014 oomd<\/a><\/noindex>. Le gestionnaire oomd est d\u00e9velopp\u00e9 par Facebook, dont les employ\u00e9s travaillent \u00e9galement sur le sous-syst\u00e8me du noyau PSI (Pressure Stall Information), permettant au gestionnaire de p\u00e9nurie de m\u00e9moire en espace utilisateur d'analyser les informations concernant le temps d'attente pour obtenir diff\u00e9rentes ressources (CPU, m\u00e9moire, entr\u00e9e\/sortie) afin d'\u00e9valuer pr\u00e9cis\u00e9ment le niveau de charge du syst\u00e8me et la nature du ralentissement.<\/p>\n

oomd est en phase finale de cr\u00e9ation d'un produit universel adapt\u00e9 \u00e0 toutes les charges de travail sans besoin d'ajustements suppl\u00e9mentaires. Une fois que les derniers composants manquants de l'interface PSI (\u00ab iocost \u00bb) seront ajout\u00e9s au noyau Linux, la soci\u00e9t\u00e9 Facebook pr\u00e9voit de transmettre oomd ou sa version simplifi\u00e9e pour inclusion dans systemd. Cela devrait se produire dans six mois \u00e0 un an. Earlyoom peut \u00eatre utilis\u00e9 dans Fedora comme solution temporaire jusqu'\u00e0 ce qu'oomd soit pr\u00eat, mais \u00e0 long terme, Pottering estime que l'avenir appartient \u00e0 oomd.<\/p>\n
