I have an arch-system running from a simple usb-stick (using ext2 file system).
I wanted to make a copy of it using f2fs-files system. So I copied the files, created directories like dev, sys, proc .
Chrooting into the new system and using pacman, with any package I tried this happens:
pacman -Su

...Since I could run "pacman -Syu" in the chroot-system, I updated the whole system with "pacstrap /mn/sdb1 -u" - so I guess everything is up to date on the host machine and the chroot-system.

Usingf2fs will not IMHO improve anything for modern SSD or USB key that have wear leveling controller that handles the flash rather well. F2FS would be useful if you access the flash directly which is not possible with usual hardware.
Anyway, I suspect you did not copy the files correctly; which has led to a corrupted system. If you want to transfer a whole installation by copying files, you can only do so properly outside the running system (for example from a boot disk). You should certainly not simply copy / from the running system because other directories are mounted under subdirectories of / (for example /proc, etc.). You could somehow see the underlying root filesystem only under /mnt/thing with a command like this:
mount --bind / /mnt/thingbut it is still preferable to copy the files from a non-running system. You should not create any directories by hand, the required /proc, /sys, etc. are already present with the good attribute on the original file system.
You should also be careful to copy all meta information in the files; I remember I had problems with "cp -a" that did not handle capabilities. I use
rsync --archive --xattrs --acls --sparse --hard-links /mnt/orig/. /mnt/copywhich I believe preserve all meta information.

Thanks for clarification. I left out directories like /proc, sys etc, but yes, I copied the files from the system which was running. And I made the proc, sys etc files manually on the target device.
I will follow you advice with concluding, that the long way wil be the shortest in the end: I'll do a fresh install.

Again I was on the wrong track: I guess the file system of the source arch installation must have been corrupted.
I did a clean new install on a f2fs-Partion with and got it booted with the help of grub-git from aur (because f2fs is still not supported by the stable version of grub in the arch repo).
I could clone this one easily using file copy .
Assuming the source usb stick is mounted on /mnt/sdb1 and the target stick is mounted on /mnt/sdc1 I did
cd /mnt/sdb1
cp -a bin dev lib lib64 mnt proc root run sbin srv sys tmp /mnt/sdc1/
cp -a -v boot etc home opt usr var /mnt/sdc1/Now I can easily do
arch-chroot /mnt/sdc1and install the bootloader, e.g.
grub-install --target=i386-pc /dev/sdcgrub-mkconfig
I did a manual edit of the /boot/grub/grub.cfg file, because the grub-mkconfig way didn't work for me. My one looks like:
set timeout=5
set default=0
menuentry "Arch linux" {
linux /boot/vmlinuz-linux root=LABEL=root_home rw rootdelay=30 net.ifnames=0 fsck.mode=force
initrd /boot/intel-ucode.img /boot/initramfs-linux.img
}Of course you should be able to use UUID instead of LABEL depending how you create your file system and of you provided a LABEL to it (I used "root_home") Further examples in the wiki are a little bid hidden, see Draft of grub wiki page by user Eschwartz
