Kernel/Removal/it

Questo articolo descrive la rimozione dei vecchi kernel.

Rimozione dei sorgenti del kernel
Dopo aver installato un nuovo kernel che funge correttamente, il kernel vecchio può essere rimosso. Per rimuovere dei vecchi sorgenti kernel, il comando emerge "--depclean" (oppure in forma breve "-c") può essere usato per rimuovere tutte le vecchie o inutilizzate versioni di uno specifico pacchetto, ad esempio per .

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 however only removes the files it installed - the files generated during the kernel build and installation remain. They can be safely removed.


 * 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 :




 * The old files in can also be removed:




 * Lastly, remove all leftover entries from your bootloader's config file.
