You’re right, except for #3: if you do ‘guix system roll-back’ and
reboot, then /var/guix/profiles/system points to a generation that’s not
the latest system-*-link but that is the currently running one.

It sounds super confusing but it’s quite intuitive I think (I hope?).

Applied now, thanks for taking a look!
