When the store overlay is mounted, other processes such as kmscon, udev and guix-daemon may open files from the store, preventing the underlying install support from being umounted. See: https://lists.gnu.org/archive/html/guix-devel/2018-12/msg00161.html. To avoid this situation, mount the store overlay inside a container, and run the installation from within that container. * gnu/build/shepherd.scm (fork+exec-command/container): New procedure. * gnu/services/base.scm (guix-shepherd-service): Support an optional PID argument passed to the "start" method. If that argument is passed, ensure that guix-daemon enters the given PID MNT namespace by using fork+exec-command/container procedure. * gnu/installer/final.scm (umount-cow-store): Remove it, (install-system): run the installation from within a container. * gnu/installer/newt/final.scm (run-install-shell): Remove the display hack.
