name: snapd type: snapd summary: Daemon and tooling that enable snap packages description: | Install, configure, refresh and remove snap packages. Snaps are 'universal' packages that work across many different Linux systems, enabling secure distribution of the latest apps and utilities for cloud, servers, desktops and the internet of things. Start with 'snap list' to see installed snaps. adopt-info: snapd # build-base is needed here for snapcraft to build this snap as with "modern" # snapcraft build-base: core22 package-repositories: - type: apt ppa: snappy-dev/image grade: stable license: GPL-3.0 confinement: strict # Note that this snap is unusual in that it has no "apps" section. # # It is started via re-exec on classic systems and via special # handling in the core18 snap on Ubuntu Core Systems. # # Because snapd itself manages snaps it must currently run totally # unconfined (even devmode is not enough). # # See the comments from jdstrand in # https://forum.snapcraft.io/t/5547/10 # There is no explicit mechanism for passing parameters/configuration through # snapcraft at snap build time, so instead the build process looks for (or # creates) the following stamp files, which influence the build process: # # - test-build - created by the CI (or the in-repo test build script), indicates # a test build with version override to 1337.* # - fips-build - created by the CI or snapd part 'pull' stage to indicate a # build with FIPS support # - fips-build-lp - only created by snapd part 'pull' stage, when the build # environment has been identified to be LP within the FIPS-CC-STIG project, # where the snapd snap recipe is named snapd-fips # parts: dynamic-linker: plugin: nil build-packages: - gawk - bison - quilt - python3-pyelftools source: https://git.launchpad.net/ubuntu/+source/glibc source-branch: ubuntu/jammy-updates source-type: git <<: - &dynamic-linker build-environment: - to amd64: - DYNAMIC_LINKER: ld-linux-x86-64.so.2 - to s390x: - DYNAMIC_LINKER: ld64.so.1 - to arm64: - DYNAMIC_LINKER: ld-linux-aarch64.so.1 - to armhf: - DYNAMIC_LINKER: ld-linux-armhf.so.3 - to riscv64: - DYNAMIC_LINKER: ld-linux-riscv64-lp64d.so.1 - to ppc64el: - DYNAMIC_LINKER: ld64.so.2 override-pull: | craftctl default QUILT_PATCHES=debian/patches quilt push -a patch -p1 <"${CRAFT_PROJECT_DIR}/build-aux/snap/local/rename-dynamic-loader-variables.patch" override-build: | rm -rf build mkdir -p build cd build unset LDFLAGS unset CPPFLAGS export CFLAGS="-pipe -O2 -g" cat <<EOF >configparms libdir=/snap/snapd/current/usr/lib/${CRAFT_ARCH_TRIPLET_BUILD_FOR} slibdir=/snap/snapd/current/usr/lib/${CRAFT_ARCH_TRIPLET_BUILD_FOR} rtldir=/snap/snapd/current/usr/lib/${CRAFT_ARCH_TRIPLET_BUILD_FOR} EOF "${CRAFT_PART_SRC_WORK}/configure" --prefix=/snap/snapd/current/usr make -j"${CRAFT_PARALLEL_BUILD_COUNT}" -C .. objdir="${PWD}" "${PWD}/linkobj/libc_pic.a" make elf/ldso_install DESTDIR="${CRAFT_PART_INSTALL}" strip "${CRAFT_PART_INSTALL}/snap/snapd/current/usr/lib/${CRAFT_ARCH_TRIPLET_BUILD_FOR}/${DYNAMIC_LINKER}" install -Dm755 -t "${CRAFT_PART_INSTALL}/usr/lib/${CRAFT_ARCH_TRIPLET_BUILD_FOR}" "${CRAFT_PART_INSTALL}/snap/snapd/current/usr/lib/${CRAFT_ARCH_TRIPLET_BUILD_FOR}/${DYNAMIC_LINKER}" stage: - usr/lib/$CRAFT_ARCH_TRIPLET_BUILD_FOR/ld*.so* runtime: plugin: nil stage-packages: - libblkid1 - libbrotli1 - libc6 - libcap2 - libexpat1 - libfreetype6 - libgcc-s1 - liblz4-1 - liblzma5 - liblzo2-2 - libpng16-16 - libseccomp2 - libudev1 - libzstd1 - squashfs-tools - xdelta3 - zlib1g - on armhf: - libteec1 - on arm64: - libteec1 stage: - -usr/lib/$CRAFT_ARCH_TRIPLET_BUILD_FOR/ld*.so* - -lib32 - -lib64 - -usr/lib32 - -usr/lib64 - -etc/ld.so.conf.d - -usr/share/man - -usr/share/lintian - -usr/share/lintian/** - -usr/lib/$CRAFT_ARCH_TRIPLET_BUILD_FOR/libnss_*.so.2 override-build: | craftctl default cp -avT "${CRAFT_PART_INSTALL}/lib/${CRAFT_ARCH_TRIPLET_BUILD_FOR}" "${CRAFT_PART_INSTALL}/usr/lib/${CRAFT_ARCH_TRIPLET_BUILD_FOR}" rm -rf "${CRAFT_PART_INSTALL}/lib/${CRAFT_ARCH_TRIPLET_BUILD_FOR}" rm -f "${CRAFT_PART_INSTALL}/lib/${DYNAMIC_LINKER}" find "${CRAFT_PART_INSTALL}/usr/share/doc" \( -not -type d -not -name "copyright" -delete \) -o \( -type d -empty -delete \) <<: - *dynamic-linker # FIXME: uncomment when https://bugs.launchpad.net/snapcraft/+bug/2097440 is fixed # override-prime: | # craftctl default # python3 "${CRAFT_PROJECT_DIR}/build-aux/snap/local/patch-dl.py" "/snap/snapd/current/usr/lib/${CRAFT_ARCH_TRIPLET_BUILD_FOR}/${DYNAMIC_LINKER}" # FIXME: remove when https://bugs.launchpad.net/snapcraft/+bug/2097440 is fixed prime-runtime: plugin: nil after: - runtime <<: - *dynamic-linker override-prime: | craftctl default CRAFT_PART_INSTALL="${CRAFT_PART_INSTALL}/../../runtime/install" \ python3 "${CRAFT_PROJECT_DIR}/build-aux/snap/local/patch-dl.py" "/snap/snapd/current/usr/lib/${CRAFT_ARCH_TRIPLET_BUILD_FOR}/${DYNAMIC_LINKER}" apparmor: plugin: autotools build-packages: - autoconf-archive - bison - flex - gettext - g++ - pkg-config - wget source: https://gitlab.com/apparmor/apparmor/-/archive/v4.0.2/apparmor-v4.0.2.tar.gz source-checksum: sha256/0b847751b8c0e2344169ec2065cad6251063c5c5ff311953e194bbf25686d981 override-build: | # For some reason, some snapcraft version remove the "build-aux" folder # and move the contents up when the data is uploaded;
