Обновление ядра и модулей

Главное отличие от разнообразных предыдущих версий – интерактивный выбор ядра из списка доступных.

Выбор неустановленного ядра влечёт его установку вместе с комплектом модулей.

При выборе ядра, уже установленного в системе предлагаются возможные взаимоисключающие действия:

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

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

30.03.09

установка kernel-headers-modules, главным образом под смену flavour
увеличена цветность

14.01.09, основное:

добавлен вызов x11setupdrv из update-kernel
учтено появление Epoch/Serial
добавлена сортировка списка по типу, опционально по версии

$PROG [options][flavour][release]

$PROG is a kernel maintenance tool. It helps to install, remove,
and switch kernels with related module infrastructures.

Both, flavour and release, are patterns to filter full kernel list.

	flavour is one of well-known, like "std-smp" or "std-def"
		or "ovz-wks" etc.

	release is somewhat more flexible, like "alt6" or "2.6.22"
		or so.

Valid options are:

	-f | -y | --yes | --assume-yes
		to force apt-get --yes

	-n | --num
		to numeric sort

	-h | --help
		to display this text
