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.
This will allow us to automate testing of the installer.
* gnu/installer/utils.scm (%client-socket-file)
(current-server-socket, current-clients): New variables.
(open-server-socket, call-with-server-socket): New procedure.
(with-server-socket): New macro.
(run-shell-command): Add call to 'send-to-clients'. Select on both
current-input-port and current-clients.
* gnu/installer/steps.scm (run-installer-steps): Wrap 'call-with-prompt'
in 'with-socket-server'. Call 'sigaction' for SIGPIPE.
* gnu/installer/newt/page.scm (watch-clients!, close-port-and-reuse-fd)
(run-form-with-clients, send-to-clients): New procedures.
(draw-info-page): Add call to 'run-form-with-clients'.
(run-input-page): Likewise. Handle EXIT-REASON equal to 'exit-fd-ready.
(run-confirmation-page): Likewise.
(run-listbox-selection-page): Likewise. Define 'choice->item' and use it.
(run-checkbox-tree-page): Likewise.
(run-file-textbox-page): Add call to 'run-form-with-clients'. Handle
'exit-fd-ready'.
* gnu/installer/newt/partition.scm (run-disk-page): Pass
#:client-callback-procedure to 'run-listbox-selection-page'.
* gnu/installer/newt/user.scm (run-user-page): Call
'run-form-with-clients'. Handle 'exit-fd-ready'.
* gnu/installer/newt/welcome.scm (run-menu-page): Define
'choice->item' and use it. Call 'run-form-with-clients'.
* gnu/installer/newt/final.scm (run-install-success-page)
(run-install-failed-page): When (current-clients) is non-empty, call
'send-to-clients' without displaying a choice window.
* gnu/installer/newt/final.scm (run-install-failed-page): Propose between
installer resume or restart. Do actually resume the installation by raising an
&installer-step-abort condition if "Resume" button is pressed. Otherwise, keep
going as the installer will be restarted by login.
* gnu/installer.scm (installer-program): Remove the associated TODO comment.
Fixes <https://bugs.gnu.org/36885>.
Reported by <lukasbf@tutanota.com>.
* gnu/installer/newt/page.scm (edit-file): New procedure.
(run-file-textbox-page): Add #:edit-button? and #:editor-locale
parameters. Remove 'file-text' and add 'edit-button', and add it
to the horizontal stacked grid when EXIT-BUTTON? is true. Wrap
body in 'loop'. Handle case where ARGUMENT is EDIT-BUTTON by calling
'loop'.
* gnu/installer/newt/final.scm (run-config-display-page): Add #:locale
parameter. Pass #:edit-button? and #:editor-locale to
'run-file-textbox-page'.
(run-final-page): Pass LOCALE to 'run-config-display-page'.
* gnu/installer/newt/final.scm (run-install-success-page): Return
'success.
* gnu/installer.scm (installer-program): Check the result of the 'final
step and reboot upon success.
Partly fixes <https://bugs.gnu.org/35399>.
* gnu/installer/user.scm (<user>)[password]: New field.
* gnu/installer/final.scm (%seed): New variable.
(integer->alphanumeric-char, random-string)
(create-user-database): New procedures.
(install-system): Call 'create-user-database'.
* gnu/installer/newt/final.scm (run-install-shell): Add #:users and pass
it to 'install-system'.
(run-final-page): Pass #:users to 'run-install-shell'.
* gnu/installer/newt/user.scm (run-user-add-page): Add password entry.
Pass its result as the 'password' field of <user>.
* gnu/installer/utils.scm (run-shell-command): Add #:locale and honor it.
* gnu/installer/newt/final.scm (run-install-shell): Add 'locale'
parameter; pass it to 'install-system'.
(run-final-page): Obtain locale from RESULT; pass it to 'run-install-shell'.
* gnu/installer/final.scm (install-system): Add 'locale' parameter; pass
it to 'run-shell-command'.
