Обновление ядра и модулей

Главное отличие от разнообразных предыдущих версий – интерактивный выбор ядра.

При выборе ядра, уже установленного в системе предлагаются три возможных [взаимоисключающих] действия:

• сделать это ядро загружаемым по умолчанию (/sbin/installkernel)
• переустановить пакет целиком
• обновить модули к нему
• удалить ядро и модули

Выбор неустановленного ядра влечёт установку его с комплектом модулей.

С момента публикации уже внесен ряд исправлений, но мне еще кое-чего не нравится. По сему – продолжение следует...
