Arch drops me to a rescue shell after kernel update

Hello everyone,

I am an Arch newbie and glad if you hold my hand for a little on this one.

Last night I did my first

pacman -Syu

and among others it also updated my kernel to whatever kernel currently in the repositories is. After that I rebooted my Linux box and yes I forgot to update my /boot/efi/EFI/arch first; now it says it can't properly read from my /boot and drops me to a rescue shell.

I have a UEFI motherboard and during installation I followed the EFISTUB instructions in the wiki; using that everything booted flawlessly on my first attempt.

So far I managed to boot from my trusted SystemRescueCD. I can access the Arch documentation via web browser in an X11 environment and I can cleanly mount my partitions and chroot, but I am troubled by the output I am seeing. The obvious solution to my newbie problem would be to go through the EFISTUB instructions in the wiki again, but I have no clue where my boot file sources are. Check this:

root@sysresccd /root % mkdir /mnt/arch-root
root@sysresccd /root % mkdir /mnt/arch-root/boot
root@sysresccd /root % mount /dev/sdc3 /mnt/arch-root 
root@sysresccd /root % mount /dev/sdc1 /mnt/arch-root/boot 
root@sysresccd /root % ls -al /mnt/arch-root/boot

root@sysresccd /root %

Why are there no vmlinuz-linux, initramfs-linux.img, and initramfs-linux-fallback.img in my /mnt/arch-root/boot ?

Why is there an EFI/* in my /mnt/arch-root/boot and not the efi/EFI/* I expect to find? It's as if one level of the file hierarchy is missing... if I mounted something incorrectly, I'd expect an empty mount point, but this phenomenon  of having something but not everything really puzzles me.

The rest seems ok as it was Feb27 when I did my intital installation of Arch and Mar6 when I did the pacman -Syu

Thanks for any help, I am really clueless right now.
