Broken system after panic during pacman -Syu

During a system upgrade my capslock started flashing and I was unable to do a thing.
I assumed it was a kernel panic.

My laptop lacking magic sq, I just hard rebooted the thing.
Fortunately the system did come up, but at least two things were broken:
glib (not glibc), which I was able to reinstall
and all files in /usr/local/zoneinfo.

What is interesting is that all symlinks in zoneinfo are missing and
pacman -Qo /usr/local/CET returns
"error: No package owns /usr/share/zoneinfo/CET".

I was able, using another machine, to learn that the package is
actually tzdata, but I'm now quite sure my system is borked to the
point where simply reinstalling all packages it knows it has may not be enough.

Any ideas how I should go forward with this?

Boot the arch installer, proceed as if installing a fresh system, but use arch-chroot to fix the problem (or pacstrap only the broken packages).

Reboot into a chroot and checkout the output from pacman -Qkk >/dev/null. It will tell which files are corrupt / missing
