[bug#35910] [PATCH] services: Add ‘/usr/bin/env’ special file.

[Tobias Geerinckx-Rice]

* gnu/services/base.scm (%base-services): Add ‘/usr/bin/env‘ to
special-files-service-type.
---

Guix,

I didn't even realise this was ‘missing’.  Is there any reason not to include it next to /bin/sh?

Sure, it's not pure, but then why provide /bin/sh when nowadays /usr/bin/env is both more common, more flexible,>

Feel free to gently enlighten me.

Kind regards,

T G-R

'course this won't work unless you, also, have the hunk

   #:use-module ((gnu packages base)
-                #:select (canonical-package glibc 
                  glibc-utf8-locales))
+                #:select (canonical-package coreutils glibc 
glibc-utf8-locales))

accidentally placed in another commit, which is unlikely.

The ‘special-files’ service, ‘extra-special-file’, and related
documentation, including a snippet for adding /usr/bin/env (info "(guix)
Base Services"), stem from this discussion:

  https://lists.gnu.org/archive/html/guix-devel/2017-02/msg00205.html

So, do people want to add /usr/bin/env by default?  :-)

Thanks,
Ludo’.

This would provide some sanity in writing scripts that
could be portable between guix and non-guix systems.

I've used this in the past to write scripts what would
work between Linux and BSD systems.
