Настройка memavaild 0.6 для сохранения отзывчивости при запуске жирных фоновых процессов

Конфигурация memavaild.conf

Для соответствующей настройки memavaild нужно добавить в конфиг /etc/memavaild.conf следующую строку:

@LIMIT  CGROUP=user.slice/user-$UID.slice/user@$UID.service/idle.slice  MIN_MEM_HIGH_PERCENT=5  RELATIVE_SHARE=0.2

Добавляем alias
