1) уверен что при самосборном ядре скорость увеличится минимум на пару секунд, исходя из этого есть вопросы:
при установке новой версии ядра остается ли какой нибудь мусор от старого, если да то как его поавтоматичней почистить
если кто ставил самосборное на ноут - расскажите эффект (сильно ли влияет на скорость)
модули в ядро вкомпилировать лучше или нет, если да то какие лучше в ядро пихать а какие нет (для еее вайфаевские например лучше с аура ставить)
2) кто-нибудь ставил initng или что нибудь подобное в арче? если да то пожалуйста про установку расскажите и настройку.
я конечно не мечтаю о пяти секундах но не 30 же ждать
когда дефолтная система почти в 2 раза быстрее грузится.3) если п.2 не подходит, то что можно в дефолтных скриптах поправить?
