Updating gentoo kernel
(use --oneshot for things you don't want to add in to the world file, like system libs for example).
Note that it's always easier to do if you keep up to date regularly rather than going for monolithic batch updates every couple of months.
Processor manufacturers release stability and security updates to the processor microcode.
But all Intel users should install the updates as a matter of course. Many AUR kernels have followed the path of the official Arch kernels in this regard. grub-mkconfig will automatically detect the microcode update and configure GRUB appropriately.
You now have a brand-new Gentoo install sitting on your Vultr machine.
This will irrevocably destroy all data on /dev/sdx Run the following command, replacing /dev/sdx with your drive, e.g. (do not append a partition number, so do not use something like /dev/sdb1) ln -s /var/lib/layman/pentoo/profiles/pentoo/base/package.accept_keywords/net-analyzer /etc/portage/package.keywords ln -s /var/lib/layman/pentoo/profiles/pentoo/base/package.use/dev-ruby /etc/portage/To merge the overlay with your current setup smoother, additional changes can be made in a usual Gentoo way by modifying files in the /etc/portage directory.
These updates must be enabled by adding as the first initrd in the bootloader config file. After installing the should be a cpio archive, as in this case.
It is advised to check whether the archive is compressed after each microcode update, as there is no guarantee that the image will stay non-compressed in the future.
