OK, now managed to get a reproducer script to kick this bug even outside the early install context. Seems like we can force this bug by either remounting OR sync'ing and dropping caches.
Attached is the reproducer script.
Run as root, we hit the error:
cat: /root-tmp/etc/.pwd.lock: Input/output error
dmesg: [ 42.415432] overlayfs: invalid origin (etc/.pwd.lock, ftype=8000, origin ftype=4000).
