downloadefi-boot-shim-debian/15+1533136590.3beb971-1.tar.gz
efi-boot-shim-debian/15+1533136590.3beb971-1.zip
* New upstream release.debian/15+1533136590.3beb971-1
- debian/patches/second-stage-path: dropped; the default loader path now includes an arch suffix. - debian/patches/sbsigntool-no-pesign: dropped; no longer needed. * Drop remaining patches that were not being applied. * Sync packaging from Ubuntu: - debian/copyright: Update upstream source location. - debian/control: add a Build-Depends on libelf-dev. - Enable arm64 build. - debian/patches/fixup_git.patch: don't run git in clean; we're not really in a git tree. - debian/rules, debian/shim.install: use the upstream install target as intended, and move files to the target directory using dh_install. - define RELEASE and COMMIT_ID for the snapshot. - Set ENABLE_HTTPBOOT to enable the HTTP Boot feature. - Update dh_auto_build/dh_auto_clean/dh_auto_install for new upstream options: set MAKELEVEL. - Define an EFI_ARCH variable, and use that for paths to shim. This makes it possible to build a shim for other architectures than amd64. - Set EFIDIR=$distro for dh_auto_install; that will let files be installed in the "right" final directories, and makes boot.csv for us. - Set ENABLE_SHIM_CERT, to keep using ephemeral self-signed certs built at compile-time for MokManager and fallback. - Set ENABLE_SBSIGN, to use sbsign instead of pesign for signing fallback and MokManager.
