Pretty cool!  It'd keep on working even if we even clean up /etc/profile
from the hardcoded defauts environment variables (say, if we merge one
of the proposed solution of https://issues.guix.gnu.org/22138).

I agree that it seems useful and important to add a monitor on the
/run/current-system as well.
