2018-06-21system: Mapped devices needed for boot do not yield Shepherd services....Fixes <https://bugs.gnu.org/31889>. Reported by Taylan Kammer <taylanbayirli@gmail.com>. * gnu/system.scm (non-boot-file-system-service)[mapped-devices-for-boot]: New variable. Remove dependencies of FS that are members of MAPPED-DEVICES-FOR-BOOT. (mapped-device-user): Rename to... (mapped-device-users): ... this. Use 'filter' instead of 'find'. (operating-system-user-mapped-devices) (operating-system-boot-mapped-devices): Use 'any file-system-needed-for-boot?' instead of looking at the first user. * tests/system.scm ("non-boot-file-system-service"): New test. Ludovic Courtès
2018-05-28system: Remove uses of the 'title' field of <file-system>....* gnu/system/install.scm (installation-os): Remove uses of the 'title' field of 'file-system'; use 'file-system-label' as appropriate. * gnu/system/vm.scm (system-disk-image, system-qemu-image): Likewise. * gnu/tests.scm (%simple-os): Likewise. * gnu/tests/install.scm (%minimal-os, %minimal-extlinux-os) (%minimal-os-on-vda, %separate-home-os, %separate-store-os) (%raid-root-os, %encrypted-root-os, %btrfs-root-os): Likewise. * gnu/build/shepherd.scm (default-mounts)[tmpfs]: Likewise. * tests/guix-system.sh: Likewise. * tests/system.scm (%root-fs): Likewise. ("operating-system-boot-mapped-devices, implicit dependency"): Likewise. Ludovic Courtès
2017-12-06gnu, doc, tests: Use ‘bootloader-configuration’ everywhere....* doc/guix.texi (Proceeding with the Installation): Replace the old-style ‘grub-configuration’ with the newer ‘bootloader-configuration’ syntax. * gnu/system/examples/vm-image.tmpl: Likewise. * gnu/system/install.scm (installation-os): Likewise. * gnu/tests.scm (%simple-os): Likewise. * gnu/tests/install.scm (%minimal-os, %minimal-os-on-vda, %separate-home-os) (%separate-store-os, %raid-root-os, %encrypted-root-os, %btrfs-root-os): Likewise. * gnu/tests/nfs.scm (%base-os): Likewise. * tests/guix-system.scm (OS_BASE, make_user_config): Likewise. * tests/system.scm (%os, %os-with-mapped-device): Likewise. Tobias Geerinckx-Rice
2017-08-23gnu: bootloader: Deprecate "device" field in favor of "target"....* gnu/bootloader.scm (<bootloader-configuration>): Deprecate "device" field in favor of "target" field. This is mostly a renaming but also a generalization to support UEFI targets being paths to a mounted partition instead of a device name. * gnu/system/examples/bare-bones.tmpl: * gnu/system/examples/desktop.tmpl: * gnu/system/examples/lightweight-desktop.tmpl: * gnu/system/examples/vm-image.tmpl: * gnu/system/install.scm: * gnu/tests.scm: * gnu/tests/install.scm: * gnu/tests/nfs.scm: * tests/system.scm: Adapt all invocations of bootloader-configuration. * guix/scripts/system.scm (perform-action): Rename device argument to bootloader-target. (process-action): Adapt caller. * doc/guix.texi (Proceeding with the Installation): * doc/guix.texi (Bootloader Configuration): Update documentation. Andy Wingo
