coreutils doesn't need to be in the profile since /usr/bin/env is linked
to (file-append coreutils "bin/env"); see in the value of %base-services
in (gnu services base), which contains:

--8<---------------cut here---------------start------------->8---
(service special-files-service-type
                 `(("/bin/sh" ,(file-append bash "/bin/sh"))
                   ("/usr/bin/env" ,(file-append coreutils "/bin/env"))))
--8<---------------cut here---------------end--------------->8---
                   

'env' looks up the command passed to it from PATH, but that's usually
satisfied if you were going to use a FHS location anyway such as
"/bin/bash".
