Kernel/Removal/ru

В этой статье описывается удаление старых ядер.

Удаление исходных текстов ядра
After a new kernel is installed and if it works satisfactorily, the old kernel can be removed. To remove the old kernel sources, emerge's --depclean option (short form -c) can be used to remove all old or unused versions of a slotted package, e.g. for.

Be sure to verify that it is not removing the sources for the currently running kernel. (See kernel upgrade article on how to upgrade.)

Protecting kernel sources
If newer kernel sources has been merged and you run --depclean before switching to the newer sources, the current sources will be removed. But if you want to stay with the current sources, this removal is not wanted, because you may need the sources e.g. for updating external kernel modules. It's therefore good practice to add the specific kernel version to your world file to protect it from --depclean operations.

Note the slot notation, using a colon instead of a dash. Every kernel version is its own slot.

Using eclean-kernel
is a simple tool for old kernel cleanup/removal. It removes both built kernel files and build directories if they're no longer reference by any preserved kernel.

For example, to keep three newest kernels around:

Manual removal
Portage, удаляет только те файлы, которые он установил - файлы, созданные во время сборки ядра и установки остаются. Они могут быть безопасно удалены.


 * When a kernel is built in the source directory, files generated during the build process remain, and are not removed by Portage:




 * During kernel setup, the kernel modules are copied to a sub directory of /lib/modules/:




 * The old files in can also be removed:




 * И наконец, удалите все оставшиеся записи из файла конфигурации вашего загрузчика.
