What’s the effect of this brokenness concretely? Is the wrong root file
system mounted, or something like that?
Could it somehow lead Guix to stumble upon an empty or missing
/etc/shadow when it boots?

There really isn’t much to log: the activation code reads
/etc/{shadow,passwd,group}, computes the list of shadow/passwd/group
entries as a function of that, and writes it.
