2020-12-15image: 'register-closure' leaves it up to the caller to deduplicate....* gnu/build/image.scm (register-closure): Remove #:deduplicate? parameter and pass #:deduplicate? #f to 'register-items'.

2020-12-15store-copy: 'populate-store' can optionally deduplicate files....Until now deduplication was performed as an additional pass after copying files, which involve re-traversing all the files that had just been copied. * guix/store/deduplication.scm (copy-file/deduplicate): New procedure. * tests/store-deduplication.scm ("copy-file/deduplicate"): New test. * guix/build/store-copy.scm (populate-store): Add #:deduplicate? parameter and honor it. * tests/gexp.scm ("gexp->derivation, store copy"): Pass #:deduplicate? #f to 'populate-store'. * gnu/build/image.scm (initialize-root-partition): Pass #:deduplicate? to 'populate-store'.

2020-12-15database: Remove #:reset-timestamps? from 'register-items'....The assumption now is that the caller took care of resetting timestamps and permissions. * guix/store/database.scm (register-items): Remove #:reset-timestamps? parameter and the call to 'reset-timestamps'. (register-path): Adjust accordingly and add call to 'reset-timestamps'. * gnu/build/image.scm (register-closure): Remove #:reset-timestamps? parameter to 'register-items'. * gnu/build/vm.scm (register-closure): Likewise. * guix/nar.scm (finalize-store-file): Adjust accordingly. * guix/scripts/pack.scm (store-database)[build]: Likewise. Ludovic Courtès
2020-12-15image: 'register-closure' assumes already-reset timestamps....* gnu/build/image.scm (register-closure): Remove #:reset-timestamps? parameter. Pass #:reset-timestamps? #f to 'register-items'. (initialize-root-partition): Adjust accordingly. * gnu/build/vm.scm (register-closure, root-partition-initializer): Likewise. Ludovic Courtès
2020-12-15store-copy: 'populate-store' resets timestamps....Until now, 'populate-store' would reset permissions but not timestamps, so callers would resort to going through an extra directory traversal to reset timestamps. * guix/build/store-copy.scm (reset-permissions): Remove. (copy-recursively): New procedure. (populate-store): Pass #:keep-permissions? to 'copy-recursively'. Remove call to 'reset-permissions'. * tests/gexp.scm ("gexp->derivation, store copy"): In BUILD-DRV, check whether 'populate-store' canonicalizes permissions and timestamps. * gnu/build/image.scm (initialize-root-partition): Pass #:reset-timestamps? #f to 'register-closure'. * gnu/build/vm.scm (root-partition-initializer): Likewise. Ludovic Courtès
2020-11-05image: Error out when passed an unsupported partition type....* gnu/build/image.scm (make-partition-image): Use 'raise' instead of 'format' when TYPE is not supported. (convert-disk-image): Remove unneeded 'begin'. Ludovic Courtès
2020-09-29image: Add support for compressed-qcow2 format....* gnu/build/image.scm (convert-disk-image): New procedure. (genimage): Remove target argument. * gnu/system/image.scm (system-disk-image): Add support for 'compressed-qcow2 image format. Call "convert-disk-image" to apply image conversions on the final image. Add "qemu-minimal" to the build inputs. (system-image): Also add support for 'compressed-qcow2. Mathieu Othacehe
2020-07-11image: Do not set journal_model=WAL for the Hurd....This fixes <https://bugs.gnu.org/42151>. * gnu/system/images/hurd.scm (hurd-initialize-root-partition): Use #:wal-mode #f in call to ... * gnu/build/image.scm (initialize-root-partition): ... this, add #:wal-mode? parameter, pass it to ... (register-closure): ... this, add #:wal-mode? parameter, pass it to ... * guix/store/database.scm (with-database): ... this, add #:wal-mode? parameter, pass it to ... (call-with-database): ... this, add #:wal-mode? parameter; when set to #f, do not set journal_model=WAL. Jan (janneke) Nieuwenhuizen
2020-06-22system: image: Remove "image-root" when building raw disk-images....The "image-root" derivation output is used as a temporary directory that is passed to mke2fs and mkdosfs later on. By merging the creation of this directory and the production of partition images, we can get rid of the derivation. As mke2fs and mkdosfs are not able to override file permissions, call those commands with fakeroot. This way, all the image files will be owned by root, even if image generation is done in an unprivilegded context. * gnu/system/image.scm (system-disk-image): Merge "image-root" and "iso9660-image" derivations so that we spare an extra derivation. Also add "fakeroot" and its runtime dependencies to the inputs. * gnu/build/image.scm (make-ext-image, make-vfat-image): Make sure that mke2fs and mkdosfs are respectively called by fakeroot. Mathieu Othacehe
2020-06-18database: 'register-items' takes an open database....* guix/store/database.scm (store-database-directory) (store-database-file): New procedures. (call-with-database): Add call to 'mkdir-p'. (register-items): Add 'db' parameter and remove #:state-directory and #:schema. (register-path): Use 'store-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.
