tore-database-file' and 'with-database', and parameterize SQL-SCHEMA. * gnu/build/image.scm (register-closure): Likewise. * gnu/build/vm.scm (register-closure): Likewise. * guix/scripts/pack.scm (store-database)[build]: Likewise. Ludovic Courtès 2020-06-09build: image: Do not call make-essential-device-nodes by default....Calling "mknod" without root permissions fails. Plus those device nodes do not appear to be needed to boot. * gnu/build/image.scm (initialize-root-partition): Do not use make-essential-device-nodes as default make-device-nodes procedure. Mathieu Othacehe 2020-06-08image: Add Hurd support....* gnu/system/image.scm (hurd-disk-image): New exported variable, (root-offset, root-label): new variables, (esp-partition, root-partition): adapt accordingly, (find-image): add Hurd support. Mathieu Othacehe 2020-05-29build: image: Fix initialize-efi-partition docstring....* gnu/build/image.scm (initialize-efi-partition): Turn BOOTLOADER-PACKAGE into GRUB-EFI. Mathieu Othacehe 2020-05-29image: Use grub-efi to install the EFI bootloader....* gnu/build/image.scm (initialize-efi-partition): Rename bootloader-package argument to grub-efi. * gnu/system/image.scm (system-disk-image): Adapt accordingly to pass grub-efi package. Mathieu Othacehe 2020-05-29image: Add bootloader installation support....* gnu/build/image.scm (initialize-root-partition): Add bootloader-package and bootloader-installer arguments. Run the bootloader-installer if defined. * gnu/system/image.scm (system-disk-image): Adapt the partition initializer call accordingly. Mathieu Othacehe 2020-05-26image: Add partition file-system options support....* gnu/image.scm (<partition>)[file-system-options]: New field, (partition-file-system-options): new exported procedure. * gnu/system/image.scm (partition->gexp): Adapt accordingly. * gnu/build/image.scm (sexp->partition): Also adapt accordingly, (make-ext-image): and pass file-system options to mke2fs. Mathieu Othacehe 2020-05-26build: image: Add support for EXT2 and EXT3 file-systems....* gnu/build/image.scm (make-ext4-image): Rename to ... (make-ext-image): ... it, and pass the file-system type to mke2fs, (make-partition-image): Adapt to call "make-ext-image" if the partition file-system is prefixed by "ext". Mathieu Othacehe 2020-05-05image: 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. * gnu/image.scm: New file. * gnu/system/image.scm: New file. * gnu/build/image: New file. * gnu/local.mk: Add them. * gnu/system/vm.scm (system-disk-image): Rename to system-disk-image-in-vm. * gnu/ci.scm (qemu-jobs): Adapt to new API. * gnu/tests/install.scm (run-install): Ditto. * guix/scripts/system.scm (system-derivation-for-action): Ditto.
