2022-12-10install: 'umount-cow-store' retries upon EBUSY....Possibly fixes <https://issues.guix.gnu.org/59884>. * gnu/build/install.scm (umount*): New procedure. (unmount-cow-store): Use it instead of 'umount'. Ludovic Courtès
2022-11-15install: Validate symlink target in evaluate-populate-directive....* gnu/build/install.scm (evaluate-populate-directive): By default, error when the target of a symlink doesn't exist. Always ensure TARGET ends with "/". (populate-root-file-system): Call evaluate-populate-directive with #:error-on-dangling-symlink #t and add comment. Maxim Cournoyer
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'. Pass #:deduplicate? #f to 'register-closure'. * gnu/build/vm.scm (root-partition-initializer): Likewise. * gnu/build/install.scm (populate-single-profile-directory): Pass #:deduplicate? #f to 'populate-store'. * gnu/build/linux-initrd.scm (build-initrd): Likewise. * guix/scripts/pack.scm (self-contained-tarball)[import-module?]: New procedure. [build]: Pass it as an argument to 'source-module-closure'. * guix/scripts/pack.scm (squashfs-image)[build]: Wrap in 'with-extensions'. * gnu/system/linux-initrd.scm (expression->initrd)[import-module?]: New procedure. [builder]: Pass it to 'source-module-closure'. * gnu/system/install.scm (cow-store-service-type)[import-module?]: New procedure. Pass it to 'source-module-closure'. Ludovic Courtès
2020-09-02install: Factorize cow-store procedure....Move the cow-store procedure from the service declaration in (gnu system install) to (gnu build install), so that it can be called from within a different context than Shepherd. * gnu/build/install.scm (mount-cow-store, unmount-cow-store): New procedures. * gnu/system/install.scm (make-cow-store): Remove it, (cow-store-service-type): adapt it accordingly.

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. Mathieu Othacehe
2020-05-05build: install: Do not set store GID....There's no need to set the store GID as is will be done by the guix-daemon, with the following snippet: if (chown(chrootStoreDir.c_str(), 0, buildUser.getGID()) == -1) throw SysError(format("cannot change ownership of ‘%1%’") % chrootStoreDir); * gnu/build/install.scm (directives): Do not set store GID. Mathieu Othacehe
2020-05-05build: install: Ignore chown exceptions....Changing ownership may require root permissions. As image can now be generated without root permissions (no VM involved), ignore those exceptions. * gnu/build/install.scm (evaluate-populate-directive): Ignore chown exceptions. Mathieu Othacehe
2020-04-11install: 'populate-root-file-system' can be passed extra directives....* gnu/build/install.scm (evaluate-populate-directive): Handle 'file' directives. (populate-root-file-system): Add #:extras parameter and honor it. Ludovic Courtès
