Oh I agree with you -- but if you switch the system profile before the
reboot (/run/current-system, not /run/booted-system) but you have
various things pointing into /run/current-system like user $PATH and
what-not, it seems like this case is already not being served correctly.
Dunno.

It seems like you want two kinds of reconfigure: one that just adds the
grub entry to make a new system the default on the next boot, and
another kind of reconfigure that also mutates /run/current-system.  Does
that make sense?
