Fixing it is a bit tricky because:

  1. The meaning of this variable is ill-defined.  Specifically, POSIX
     says it =E2=80=9Cis the value for the PATH environment variable that f=
inds
     all standard utilities.=E2=80=9D  By =E2=80=9Cstandard utilities=E2=80=
=9D, surely they must
     be talking of =E2=80=98guile=E2=80=99, =E2=80=98guix=E2=80=99, =E2=80=
=98herd=E2=80=99, and a couple of others, but
     we can=E2=80=99t be sure.  ;-)

     http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/unistd.h.html

  2. If CS_PATH refers to Coreutils, then that means that libc refers to
     Coreutils, which is inconvenient at best.

  3. We could set CS_PATH to /run/current-system/profile/bin but that
     wouldn=E2=80=99t work on foreign distros.

So I=E2=80=99m inclined to leave things as is.

Did you find a situation where the invalid value was causing troubles?

Thanks,
Ludo=E2=80=99.
