Systemd, sd-vconsole switches the initramfs boot environment from a classic BusyBox script setup over to a systemd-managed process.
The
systemd hook completely replaces both base and udev. It builds an
initramfs that starts a mini-systemd instance to handle device discovery
and orchestration instead of relying on older BusyBox shell scripts.
Without base, you drop the traditional BusyBox emergency recovery shell.
If the system undergoes a catastrophic boot failure, you will instead
drop into a systemd-managed emergency shell. Because microcode is listed
after autodetect in your configuration,
mkinitcpio will only pack
the microcode matching your specific local processor model. If you had
placed it before autodetect, it would build a universal image containing
every Intel and AMD microcode patch available. This permits you to
completely strip out any initrd=...-ucode.img references out of your
bootloader configuration (like systemd-boot or GRUB) because the
microcode is safely nested directly inside the unified image. HOOKS below represents a modern, optimized, pure systemd-based initramfs layout that strips away legacy configuration defaults
