Hello,

I am trying to use =E2=80=98guix pack=E2=80=99 to provide my colleagues an =
easy to use
compilation environment to run with Docker.  My command to create the
container image is the following

  $ guix pack -f docker -S /bin=3Dbin gcc-toolchain bash cmake make pkg-con=
fig python@2 coreutils eigen jsoncpp googletest

Then I run that image like this:

  $ IMAGE=3D`docker load -i docker-pack.tar.gz | cut -d' ' -f3`=20
  $ docker run -it $IMAGE  /bin/bash

in order for the compilation environment to be fully ready I need to
source the /gnu/store...-profile/etc/profile for things like
CMAKE_PREFIX_PATH, LIBRARY_PATH, ...

While one obvious available solution is to add an extra symlink =E2=80=98-S
/etc/profile=3Detc/profile=E2=80=99 and then source it manually.  I was thi=
nking
that maybe 'guix pack -f docker' could set the =E2=80=98Env=E2=80=99 part i=
n the
=E2=80=98config.json=E2=80=99 [1] with the appriopriate environment variabl=
es
automatically.

I would like to know if it would be a good idea, and if it is easily
doable?

Thanks.
