I have tried mount /dev/sda3 as the root directory. And I try one thing
before chroot:
> #mkdir /mnt/bin
> #cp /bin/* /mnt/bin
> #arch-chroot /mnt
> Now I can go to the chroot jail. And surprised to me, I run the following
command, and I don't see any fails:

> #rmdir /bin
> #pacman -Syu mkinitcpio systemd linux

If that should work, then try upgrading filesystem asap, and expect many
'/usr/bin/file already exists in filesystem' errors on subsequent updates.
Make sure, that they are unowned according to pacman (pacman -Qo
/path/to/file), and remove them before continuing.
Also make sure to never reboot between removing the files and upgrading
these packages.
