environment: Add ‘--writable-root’ and default to read-only root.
This is an incompatible change where the root file system in
‘guix shell -C’ is now read-only by default.
* guix/scripts/environment.scm (show-environment-options-help)
(%options): Add ‘--writable-root’.
* guix/scripts/environment.scm (setup-fhs): Invoke /sbin/ldconfig; moved
from…
(launch-environment): … here.
(launch-environment/container): Add #:writable-root? and pass it to
‘call-with-container’. Move root file system setup to #:populate-file-system.
(guix-environment*): Honor ‘--writable-root’.
* tests/guix-environment-container.sh: Test it.
* doc/guix.texi (Invoking guix shell): Document ‘--writable-root’.
(Debugging Build Failures): Mention it before “rm /bin/sh”.
