Oh I have no idea what those say, I just thought I might as well include them when the error message told me it got dumped. =P
Alright, that very much seems like the right direction, thank you!
I followed the pacman wiki (Pacman crashes during an upgrade) and ran into a bunch of “error: failed retrieving file” from mirrors. The servers were able to be pinged, I doublechecked the mirrorlist and ended up finding this thread over on the arch forums that seemed to describe this precise issue & a working solution:
pacman-key --init && pacman-key --refresh-keys
pacman --root /mnt --cachedir /mnt/var/cache/pacman/pkg -Syu
…and via that I was able to update the system. I am now able to access pacman commands just fine via the live medium & arch-chroot. No more Bus errors!
However: After trying to boot the system I ran into a “initramfs-linux.img not found”-error, tried again with fallbacks and I was greeted with the exact same issue that made me open this thread to begin with: https://i.imgur.com/vEgwaP5.jpg
pacman -Syu via arch-chroot from the live medium gave me this when a small update was pushed:

I would assume that the ldconfig issues are (harmless/unrelated) results of the (apparently very much failed) update and would be fixed by reinstalling the respective packages. Please correct me if I’m wrong there.
The only other idea I got from my google-fu was checking the output of LC_ALL=C pacman -Qk | grep -v ', 0 altered files' which resulted in exactly one entry with missing files that sounds a little bit terrifying to mess with:
grub: 1104 total files, 4 missing files
No idea if that is the cause of the issue on boot but maybe that’s something we can find out somehow?
Where do I go from here?
