When I install archlinux, i met some fails warning, and I want to why

when I install archlinux, i met a fault :

Failed to open file "/sys/devices/system/cpu/microcode/reload": Read-only file system
error: command failed to execute correctly

i can see this when I type : "pacstrap /mnt base base-devel linux linux-header linux-firmware " and also after "pacman -S grub efibootmgr networkmanager network-manager-applet wireless_tools wpa_supplicant dialog os-prober mtools dosfstools base-devel linux-headers dhcpcd"
This fail warning won't infect the installation.

And then after my installing arch (but without installing Desktop environment, like gnome) I can see:
[Failed] Failed to start Load/Save Screen Backlight Brightness of backlight: ...

These two faults won't infect the archlinux, but they make me feel uncomfortable. So is there anyone can tell me what's the problem? and why they happen?

Thanks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Have you tried installing the https://wiki.archlinux.org/title/Microcode package for your processor?

From https://github.com/archlinux/svntogit-p … k/PKGBUILD

  # Trigger a microcode reload for configurations not using early updates
  echo 'w /sys/devices/system/cpu/microcode/reload - - - - 1' |
    install -Dm644 /dev/stdin "${pkgdir}/usr/lib/tmpfiles.d/${pkgname}.conf"

The current Arch linux kernels do not support late loading which used a deprecated interface,  the linux-firmware package still tries to force such a reload.

yes, I installed. In fact I type "pacstrap /mnt base base-devel linux linux-firmware intel-ucode ntfs-3g vi vim" at the beginning.
