Reported by pelzflorian (Florian Pelz) <pelzflorian@pelzflorian.de>.
Previously, the 'modprobe' executable would try and fail to load the
module from /lib/modules/*. Set 'LINUX_MODULE_DIRECTORY' to make sure
'modprobe' looks for the module in the right place.
* gnu/system/install.scm (uvesafb-shepherd-service)[modprobe]: New

In 'start' method, invoke it instead of KMOD/bin/modprobe.
This file was added in fe1cd098d2 but it's
not referenced from anywhere, not even gnu/local.mk. Furthermore, we
don't normally add full OS examples for the purposes of illustrating the
use of a single service.
* gnu/system/examples/yggdrasil.tmpl: Remove.
Previously, copying the image would consume a lot of space and was
I/O-intensive, to the point that the marionette connection timeout of
20s could be reached when running tests like "docker-system".

'-drive' option.
(system-qemu-image/shared-store-script)[copy-image]: New variable.

Rationale: It is only used in INSTALLATION-OS and doesn't make sense to be

Cross-building a docker image with:
$ guix system image --image-type=docker --target=aarch64-linux-gnu os.scm
results in an image where the architecture declared in its config.json is
the host architecture rather than the target one. The binaries are
correctly cross-compiled, so the image can be loaded and used despite the
warning message shown by docker:
$ docker load -i vcal7bvsqcijchifhqdvprpd1niqh8sk-docker-image.tar.gz

Make the operating-system field mandatory as creating an image without it

Regression introduced in 400c9ed3d7.
Previously, for an encrypted /home (say), "cryptsetup open" would be

These changes broke the creation of the 'linux-modules-database' for all kernel
series besides 5.15, 5.4, and 5.10, like this:
------
gnu/build/linux-modules.scm:257:5: kernel module not found "framebuffer_coreboot" "/gnu/store/yff45fr6q93mw44zdql9ffr95zcvwxcn-linux-libre-4.9.299/lib/modules"
------
We should support the coreboot framebuffer, but we need to test that change more
completely before deploying it.
This effectively reverts the following commits:
1dfe8c3721 "gnu: linux-libre: Build simplefb into all x86{,_64} kernels."
bc09e7ab56 "gnu: linux-libre: Support the Coreboot framebuffer."
Fixes <https://issues.guix.gnu.org/52667> "System reconfiguration fails to build
linux-modules.drv".
This is a follow-up to 49599fab56.
Fixes: <https://issues.guix.gnu.org/52908>.
* gnu/services/xorg.scm (set-xorg-configuration)[login-manager-service-type]:
When the current system or target system begins with the string "x86_64", use
gdm-service-type as before; otherwise, use sddm-service-type.
* gnu/system/examples/vm-image.tmpl (services): Add sddm-service-type to the
list of service types to remove.
* gnu/system/examples/desktop.tmpl: Only use gnome-desktop-service-type and
the default login manager in set-xorg-configuration when the target system is
x86_64.
Fixes <https://issues.guix.gnu.org/52539>.
Reported by Jacob First <jacob.first@member.fsf.org>.
* gnu/build/accounts.scm (allocate-passwd): Add comment as to why
'real-name' is taken from PREVIOUS. Add (not system?) to the
condition.
* gnu/system.scm (operating-system-etc-service) <login.defs>: Add
"CHFN_RESTRICT".
* gnu/system.scm (%setuid-programs): Add "chfn".
* gnu/system/pam.scm (base-pam-services): Add "chfn".
* doc/guix.texi (User Accounts): Document it.
This attempts to mitigate <https://issues.guix.gnu.org/52667>.
It makes linux-libre@5.15 consistent with older versions which do not
support a modular simplefb, allowing a single %base-initrd-modules
simple list for all of them.
Unlike CONFIG_FB_SIMPLE=m, CONFIG_FB_SIMPLE=y conflicts with
CONFIG_DRM_SIMPLEDRM, so the latter is now disabled. Let us hope it is
not missed.
* gnu/packages/aux-files/linux-libre/5.15-i686.conf,
gnu/packages/aux-files/linux-libre/5.15-x86_64.conf:
Unset CONFIG_DRM_SIMPLEDRM to build in CONFIG_FB_SIMPLE=y.
* gnu/system/linux-initrd.scm (default-initrd-modules):
Remove "simplefb".
This code duplicates the (gnu system image) and (gnu build image) code. Using
VM for image generation is not needed, not portable and really slow. Remove
all the VM image generation code to make sure that only the image API is used.
* gnu/build/vm.scm: Remove it. Move the qemu-command procedure to ...
* gnu/build/marionette.scm: ... here.
* gnu/local.mk (GNU_SYSTEM_MODULES): Adapt it.
* tests/modules.scm: Ditto.
* gnu/tests/install.scm: Ditto.
* gnu/system/vm.scm: Adapt it and remove expression->derivation-in-linux-vm,
qemu-img, system-qemu-image/shared-store and system-docker-image procedures.
* doc/guix.texi (G-Expressions): Adapt it.
Also add a volatile? argument to the virtual-machine record. When volatile? is
true generate a QEMU script that mounts an overlay on top of a read only
storage. When volatile? is false, use a persistent, read-write storage.
* gnu/system/vm.scm (common-qemu-options): Add a rw-image? argument to use a
persistent storage.
(system-qemu-image/shared-store-script): Add a volatile? argument and honor
it. Use the image API to build the QEMU image.
(<virtual-machine>)[volatile?]: New field.
(virtual-machine-compiler): Pass the volatile? argument to the
system-qemu-image/shared-store-script procedure.
Without this, the kernel cannot write to the display until the
full-featured driver module (often i915) is loaded from the root file
system.
If the root file system is encrypted, the initrd's passphrase prompt
won't make it to the screen, and the fully responsive system will appear
frozen whilst waiting for user input.

Thanks to Guillem Jover <guillem@debian.org> on the OFTC's #debian-dpkg

Letting GNU Tar recursively walk the complete files hierarchy side-steps the
risks associated with providing a list of file names:
1. Duplicated files in the archive (recorded as hard links by GNU Tar)
2. Missing parent directories.
The above would cause dpkg to malfunction, for example by aborting early and
skipping triggers when there were missing parent directories.
* guix/scripts/pack.scm (self-contained-tarball/builder): Do not call
POPULATE-SINGLE-PROFILE-DIRECTORY, which creates extraneous files such as
/root. Instead, call POPULATE-STORE and INSTALL-DATABASE-AND-GC-ROOTS
individually to more precisely generate the file system. Replace the list of
files by the current directory, "." and streamline the way options are passed.
* gnu/system/file-systems.scm (reduce-directories): Remove procedure.
* tests/file-systems.scm ("reduce-directories"): Remove test.
Tar translate duplicate files in the archive into hard links. These can cause
problems, as not every tool support them; for example dpkg doesn't.
