2020-09-10installer: final: Introduce call-with-mnt-container....* gnu/installer/final.scm (call-with-mnt-container): New procedure,
(install-system): use it instead of call-with-container, to make sure that the
container is not jailed.
Mathieu Othacehe


2020-09-02installer: Run the installation inside a container....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.

2020-06-16installer: final: Remove restart-service procedure....* gnu/installer/final.scm (umount-cow-store): Remove "restart-service" that is
now provided by (gnu services herd).

2020-06-13install: final: Add some logging....* gnu/installer/final.scm (umount-cow-store): Add some logging.

2020-06-09installer: final: Dump "guix system init" command output when testing....When debugging the installation tests, it can be very handy to be able to read
"guix system init" command output.

* gnu/installer/final.scm (install-system): Dump installation command output
to the console when running the installation tests.

2020-06-09installer: final: Remove left-over pk call....* gnu/installer/final.scm (kill-cow-users): Remove pk call.
Mathieu Othacehe


2020-06-05installer: final: Add some extra logging....* gnu/installer/final.scm (kill-cow-users): Log the killed process name,
(umount-cow-store): inform that we are umounting the cow-store.
Mathieu Othacehe


2020-03-23installer: Fix cow-store umount issue....* gnu/installer/final.scm (kill-cow-users): Ignore exception that could be
raised if a process disappears between reading its pid and its maps file.
Mathieu Othacehe


2020-03-05installer: Fix cow-store umount....This fixes <https://bugs.gnu.org/39712>.

The guix-daemon was preventing the cow-store umount, so restart it.  Some
udevd workers, using cow-store files might also still be around, so have some
umount retries.

* gnu/installer/final.scm (kill-cow-users): New procedure,
(umount-cow-store): restart guix-daemon and kill all processes started from
within the cow-store before trying to umount the store overlay. Also try 5
times to umount the overlay in case it is still busy.

2020-03-05installer: Honor /tmp/installer-system-init-options....* gnu/installer/final.scm (install-system): Honor
"/tmp/installer-system-init-options".
Ludovic Courtès


2020-03-05installer: Run commands without hopping through the shell....* gnu/installer/utils.scm (run-shell-command): Rename to...
(run-command): Remove call to 'call-with-temporary-output-file' and hop
through Bash.  Expect COMMAND to be a list of strings rather than a
string.
* gnu/installer/final.scm (install-system): Turn INSTALL-COMMAND into a
list of strings and pass it to 'run-command'.
* gnu/installer/newt/page.scm (edit-file): Likewise.

2020-02-12installer: Remove the cow-store overlay after system installation....Fixes <https://issues.guix.info/issue/39217>.
Fixes <https://issues.guix.info/issue/38447>.

* gnu/installer/final.scm (umount-cow-store): New procedure ...,
(install-system): ... used here, to remove the store overlay so that the
target device is not seen as busy during further umount calls.
Mathieu Othacehe


2019-12-29installer: Pass '--fallback' to 'guix system init'....Fixes <https://bugs.gnu.org/38608>.
Reported by Nathan Dehnel <ncdehnel@gmail.com>.

* gnu/installer/final.scm (install-system): Pass '--fallback' to 'guix
system init'.
