Manjaro not only supports the use of ''multiple'' kernels (selectable from the boot screen), but allows easy access to the '''very latest ''bleeding edge''''' kernels as well. This is undertaken through use of Manjaro's own ''MHWD-kernel'' (Manjaro Hard-Ware Detection) command.

The optional '''rmc''' ('''<u>r</u>'''e'''<u>m</u>'''ove '''<u>c</u>'''urrent) component is of vital importance. Using this will result in your existing kernel being deleted upon the installation of the new kernel. Otherwise, if it is not used, then the existing kernel will be kept, and will be selectable alongside the new kernel at the boot screen. '''It is recommended - especially if updating to the latest bleeding edge kernel - to keep your old one, even if only for a short time afterwards'''. This the safer option, and the old kernel can be easily removed when satisfied with the stability and functionality of the new one. | The optional '''rmc''' ('''<u>r</u>'''e'''<u>m</u>'''ove '''<u>c</u>'''urrent) component is of vital importance.

Either way, Manjaro will automatically configure the new kernel for you, ready for immediate use. Once completed, close the terminal and re-boot the system for the change to take effect. | Either way, Manjaro will automatically configure the new kernel for you, ready for immediate use.
