* installer: Load uvesafb kernel module.Florian Pelz2020-04-11
| | | | | | | | | | | | | | | Fixes <https://bugs.gnu.org/40538>. Machines without Kernel Mode Setting (those with many old and current AMD GPUs, SiS GPUs, …) need uvesafb to show the GUI installer. Some may also need a kernel parameter like nomodeset or vga=793, but we leave that for the user to specify in GRUB. * gnu/system/install.scm (uvesafb-shepherd-service): New procedure. (uvesafb-service-type): New variable. (%installation-services): Add it. Co-authored-by: Ludovic Courtès <ludo@gnu.org>

| | | | | | | | | This is a followup to 1540075c790dfaeff52c93392f2fc63b9e23b77e. The mistake had no effect on prior Guile versions but it's visible since Guile 3.0.1 and the fix for <https://bugs.gnu.org/39634>. * gnu/system/vm.scm (operating-system-uuid): Hash a list of 'file-system-digest' values, not the 'file-system-type' procedure.

* system: Remove custom 'config-file service from "vm-image.tmpl".Ludovic Courtès2019-12-07
| | | | | | | | | | This example is broken since commit 99c45877a984dd0148151b2e304afef6fb04f1a5 (wrong file name passed to 'local-file'), and its functionality is superseded by the upcoming 'provenance-service-type'. * gnu/system/examples/vm-image.tmpl (this-file): Remove. <services>: Remove 'config-file service.
* install: Pass 'local-file' literal strings for proper resolution.Ludovic Courtès2019-12-01
| | | | | | | | | This is a followup to 99c45877a984dd0148151b2e304afef6fb04f1a5, which introduced a regression: "guix system build gnu/system/install.scm" would fail to find the .tmpl files. * gnu/system/install.scm (/etc/configuration-files)[file]: Remove. [directory]: Use 'local-file' with a literal string.
* system: vm: Support cross-compilation.Mathieu Othacehe2019-12-01

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Guile-JSON 3.x is incompatible with Guile-JSON 1.x, which we relied on until now: it maps JSON dictionaries to alists (instead of hash tables), and JSON arrays to vectors (instead of lists). This commit is about adjusting all the existing code to this new mapping. * m4/guix.m4 (GUIX_CHECK_GUILE_JSON): New macro. * configure.ac: Use it. * doc/guix.texi (Requirements): Mention the Guile-JSON version. * guix/git-download.scm (git-fetch)[guile-json]: Use GUILE-JSON-3. * guix/import/cpan.scm (string->license): Expect vectors instead of lists.

* linux-container: Compute essential services for THIS-OPERATING-SYSTEM.Ludovic Courtès2019-05-15
| | | | | | | | | | | | | | | | | | Previously, the 'essential-services' would correspond to the initial, non-containerized OS. Thus, all the file systems removed in 'container-essential-services' would actually still be there because the essential services would be computed on the non-containerized OS. This is a followup to 69cae3d3356a69b7fe69481338f760545995485e. * gnu/system/linux-container.scm (container-essential-services): Call 'operating-system-default-essential-services' to get the baseline services. (containerized-operating-system): Pass THIS-OPERATING-SYSTEM, not OS, to 'container-essential-services'. Add a dummy root file system to 'file-systems'. (container-script)[mountable-file-system?]: New procedure. Use it.
* linux-container: Do not add %CONTAINER-FILE-SYSTEMS to Docker image OSes.Ludovic Courtès2019-05-15
| | | | | | | | | | | | | | | Previously, 'guix system docker-image' would end up providing an OS that would try to mount all of %CONTAINER-FILE-SYSTEMS as well as /gnu/store, which is bound to fail in unprivileged Docker. This patch makes it so that 'guix system container' still gets those file systems, but 'guix system docker-image' doesn't. * gnu/system/linux-container.scm (containerized-operating-system): Add #:extra-file-systems parameter and honor it. Do not include %STORE-MAPPING and SHARED-NETWORK-FILE-MAPPINGS. (container-script): Add %STORE-MAPPING and optionally NETWORK-MAPPINGS to MAPPINGS and pass #:extra-file-systems.
* vm: Auto-detect if inputs should be registered.Maxim Cournoyer2019-05-13
| | | | | | | | | | | | | | | | | | | | | The default value of the argument REGISTER-CLOSURE? of the ISO9660-IMAGE, QEMU-IMAGE and SYSTEM-DOCKER-IMAGE procedures can be computed automatically, since the operating-system definition is available in its context. When the operating-system definition does not contain the GUIX-SERVICE-TYPE, do not register the closure in the database of Guix, as it takes time and doesn't serve a purpose. * gnu/system/vm.scm (has-guix-service-type): Add predicate. (iso9660-image)[register-closures?]: Use it to compute the argument's default value. (qemu-image)[register-closures?]: Likewise, and update docstring. (system-docker-image)[register-closures?]: Likewise. (system-disk-image): Do not explicit a value for the REGISTER-CLOSURES? argument of the ISO9660-IMAGE and QEMU-IMAGE procedure calls, so that its default value is used instead. * guix/scripts/system.scm (system-derivation-for-action): Do not explicit a value for the REGISTER-CLOSURES? argument of the SYSTEM-DOCKER-IMAGE procedure call, so that its default value is used instead.
