Re: Add /usr/bin/env by default in guixsd?

Hi!

Sorry for the delay.  I secretly hope somebody would answer, but this is
such a hot topic that nobody dared.  ;-)

For the record this has been discussed in the past:

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

There was no clear consensus.

Of course there are simple ways to add it, several of which were given
in the thread.

The subject does come up every once in a while though, so we really need
to address it one way or another.  :-)

First we need a simple ‘special-files’ service or something (for /bin/sh
and /usr/bin/env).

Then the whole battle will be about what the default should be.  I used
to be affiliated with the “no way!” party on this topic, but I
considering changing my mind.  :-)  Especially that it does not matter
that much, after all.

Ricardo, anyone, thoughts?
