Translations:Kernel/Removal/18/en

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.
