Right.  The ‘guix run’ script I sent doesn’t try to build things; it
just takes whatever is in $PATH (which has to be in the store,
ultimately) and runs it.

You still have to explicitly run ‘guix run icecat’, which isn’t great:
if you’re using GNOME Shell and clicking on the icon, you don’t get to
run it in a containerized environment.
