I never got around to implementing this, but I think we should use
some sane defaults to make 'guix environment' save and load
environments without the user having to figure out a bunch of flags.
For example, running 'guix environment' with no flags should
automatically load up the saved profile in the current directory and
instantiate it.  I know about --root, but I never actually use it
because it's kind of a pain.  I'd use persistent environments all the
time if it "just worked".
