On help-guix I initiated a conversation on using IceCat within a container
(<87vag2wopo.fsf@gnu.org>).  This covers some of the lower-level concepts I
was thinking off.  Specifically:

0. The ability to hide the user (and home directory) from procsses within the
   container.  This includes rewritting mapped paths;
1. Suppressing the behavior of automatically sharing cwd; and
2. Linking $GUIX_ENVIRONMENT to ~/.guix-profile.

The first two are for privacy (#1 is for conveinence, since creating an empty
dir just to cd into it is a bit klugy as a workaround).  #2 was motivated by
my needs with font-config, but I can imaging that it'd be useful elsewhere
as well.  It only really makes sense if you're not sharing your home
directory.

  scripts: environment: Add --link-profile.
  scripts: environment: Add --user.
  scripts: environment: Add --no-cwd.
