Create a symlink /usr/bin/env by default in GuixSD?

Create a symlink /usr/bin/env by default in GuixSD?

[Mekeor Melire]

/bin/sh is often used in shebangs. I guess that's why GuixSD by default
creates that symlink which points to /gnu/store/HASH-bash-VERSION/bin/sh
which again is a symlink pointing
to /gnu/store/HASH-bash-VERSION/bin/bash.

/usr/bin/env is also used very often in shebangs. Wouldn't it make
sense to also create that symlink? Maybe
to /run/current-system/profile/bin/env? Maybe optionally, maybe by
default?

Until we have found a solution for this, I suggest we mention
this issue together with some possible solutions in the manual.

This is what I do.

Hi!

Please take a look at the previous discussion on this topic:

  https://lists.gnu.org/archive/html/guix-devel/2015-11/msg00414.html

In short, there’s no consensus, but it’s not much of a problem because
people can add it for themselves:

  mkdir -p /usr/bin
  cd /usr/bin
  ln -s /run/current-system/profile/bin/env

We could add a ‘/usr/bin/env-service’ or something to facilitate it.

I have a preference for keeping the default unchanged, though.
