Until now, the read-only file system set up by ‘call-with-container’ would always be writable. With this change, it can be made read-only. With this patch, only ‘least-authority-wrapper’ switches to a read-only root file system. * gnu/build/linux-container.scm (remount-read-only): New procedure. (mount-file-systems): Add #:writable-root? and #:populate-file-system and honor them. (run-container): Likewise. (call-with-container): Likewise. * gnu/system/linux-container.scm (container-script): Pass #:writable-root? to ‘call-with-container’. (eval/container): Add #:populate-file-system and #:writable-root? and honor them. * guix/scripts/environment.scm (launch-environment/container): Pass #:writable-root? to ‘call-with-container’. * guix/scripts/home.scm (spawn-home-container): Likewise. * tests/containers.scm ("call-with-container, mnt namespace, read-only root") ("call-with-container, mnt namespace, writable root"): New tests.
