| 2020-05-05 | Merge branch 'master' into core-updates | Marius Bakke |
| 2020-05-05 | image: Add a new API....Raw disk-images and ISO9660 images are created in a Qemu virtual machine. This
is quite fragile, very slow, and almost unusable without KVM.
For all these reasons, add support for host image generation. This implies the
use new image generation mechanisms.
- Raw disk images: images of partitions are created using tools such as mke2fs
and mkdosfs depending on the partition file-system type. The partition
images are then assembled into a final image using genimage.
- ISO9660 images: the ISO root directory is populated within the store. GNU
xorriso is then called on that directory, in the exact same way as this is
done in (gnu build vm) module.
Those mechanisms are built upon the new (gnu image) module.

| 2020-04-29 | tests: install: Fix device usage....This is a follow-up of a860eddbbddeae5d3b6fe084e29ac9fafd2d6f02. Guided
installation tests are now run from an ISO image. Hence the main block device
is vda and not vdb anymore.
* gnu/tests/install.scm (installation-target-os-for-gui-tests): Use
%minimal-os-on-vda instead of %minimal-os.
(%minimal-os-on-vda): Make sure that it replicates the config of %minimal-os.

| 2020-04-29 | tests: install: Fix gui-installed-os test....This is a follow-up of a860eddbbddeae5d3b6fe084e29ac9fafd2d6f02. If using an
ISO, the main disk is vda and not vdb anymore.
* gnu/tests/install.scm (installation-target-os-for-gui-tests): Use vda2 as
swap partition.
| Mathieu Othacehe |
| 2020-04-29 | tests: install: Increase virtual machine RAM....It seems that 'guix system init' is consuming more than the 800M of RAM
currently allocated. Until this is understood, bump the limit to 1.2G.
Reported here:

| 2020-03-22 | tests: install: Abort when one installation step fails....When marionette-eval calls fail in gui-test-program, the installation
continues which results in two scenarios:
- hang forever at the next marionette-eval call,
- keep going and start a broken installation, which is annoying because it
clears the terminal and hides the error.
Make sure that gui-test-program is exited with #f return code when one of the
marionette-eval calls fail.
* gnu/tests/install.scm (gui-test-program): Add a new macro
"marionette-eval*". Throw an exception when one on the marionette-eval calls
fail.

| 2020-03-19 | tests: Accept manual installation scripts that exit with SIGTERM....Fixes <https://bugs.gnu.org/39926>.
Reported by Maxim Cournoyer <maxim.cournoyer@gmail.com>.
Previously we'd error out if the installation script exits with
non-zero, which was the case because the 'reboot' program would
typically not get a reply, and thus would eventually be killed by PID 1
as the system is brought down.
* gnu/tests/install.scm (run-install)[install]: Expect SCRIPT to exit
with SIGTERM in addition to exiting with zero.
