OK.

Yeah your expectations for ‘guix system reconfigure’ were too high I
guess.  ;-)

Seriously, I don’t think we’d want it to automagically migrate the
store.

Maybe it could check whether the root partition in the OS declaration is
the same as the one that holds the current store, but I’m not sure if
that can be done reliably.  Thoughts?
