Hello, I believe I tested the proper series but still had the failure on armhost: https://autobuilder.yoctoproject.org/typhoon/#/builders/127/builds/3398/steps/15/logs/stdio On 22/05/2024 16:11:49+0200, Johannes Schneider via lists.openembedded.org wrote: > systemd-sysext allows to overlay another image (or multiple) ontop of > a "base-image" = the current rootfs, via the use of overlayfs; to add > tools and features meant for development purposes. > > To quote the documentation on systemd-sysext: > " ...addition in order to make debugging/development easier).

Hoi, yes - v10 is the current one; and thanks for getting back with... yet another build failure :`-) i'm still struggling to get a setup to reproduce the issue with that particular build host... too many layers of MACHINEs and virtualization but this time i might have a clue/an idea: the error " Command 'opkg <snip> list-installed' returned non-zero exit status 255: " 255 -> usually is a 'foreign architecture' error; e.g. the tests happens to call the opkg from within the core-image-minimal-quemuarm64 instead of the correct one = opkg-native this would also explain why the dpkg and rpm tests succeed - there the correct sysroot is used, and neither dpkg nor rpm are part of the image running the build; but the ipk test fails because there happens to be already a "wrong"/other opkg in PATH i'll compare other users of runCmd, and dig some more -> expect a v11 :-D gruß Johannes
Hi, JOhannes, what's the status of this patchset? I'd like to start experimenting with system extensions and this looks like the place to start. /Ola On Wed, May 22 2024, Johannes Schneider via lists.openembedded.org wrote: > systemd-sysext allows to overlay another image (or multiple) ontop of > a "base-image" = the current rootfs, via the use of overlayfs; to add > tools and features meant for development purposes. > > To quote the documentation on systemd-sysext: > " ...addition in order to make debugging/development easier).

Hoi, > Hi, > > Johannes, what's the status of this patchset? the status is: it's working (locally) since around v6 but some combination of the testing CI where failing, which led to back-n-forth up to v11 which was AFAICT almost there, but then the patchstack was dropped :'-( > I'd like to start experimenting > with system extensions and this looks like the place to start. please do, more voices that use the feature might get it picked up again :-) > >/Ola On Wed, May 22 2024, Johannes Schneider via lists.openembedded.org wrote: > systemd-sysext allows to overlay another image (or multiple) ontop of > a "base-image" = the current rootfs, via the use of overlayfs; to add > tools and features meant for development purposes. > > To quote the documentation on systemd-sysext: > " ...addition in order to make debugging/development easier).

systemd-sysext allows to overlay another image (or multiple) ontop of a "base-image" = the current rootfs, via the use of overlayfs; to add tools and features meant for development purposes. To quote the documentation on systemd-sysext: " ...addition in order to make debugging/development easier). System extension images should not be misunderstood as a generic software packaging framework, ..." To build a lean image, that only holds packages that are not already part of the base-image, a snapshot of the package-database is taken after the installation of the base-rootfs is done, and picked up again when collecting the rootfs of such a extension image. with all this in place an example usage could look like this: some-core-image.bb inherit core-image IMAGE_GEN_PKGDBFS = "1" extending-image.bb inherit image-sysext IMAGE_FSTYPES = "squashfs" IMAGE_BASE_PKGDB = "some-core-image" # the above pointing at a package-db similar to: # build/deploy/images/$MACHINE/some-core-image-$MACHINE-20240210172305-pkgdb.rootfs.tar.gz then on the device, running some-core-image, with the extension image placed at FN: $> ln -s "$FN" /run/extensions/$(basename $FN).raw $> systemd-sysext list $> SYSTEMD_LOG_LEVEL=debug systemd-sysext merge As long as the VERSION_ID of the extension image matches the os-release in the base image, the above commands return sucessfully; for details on the compativility check see the docs for systemd-sysext. ========= changes with v2: rebase from 'kirkstone' onto 'master' changes with v3: incorporate review suggestions for simplification add task dependency handling add oe-selftest for the pkgdb handling add variable documentation and some more comments, and examples in the commit-msg changes with v4: rebase onto 'master' => no functional changes fixed patchtest findings changes with v5: rebase onto 'master' add '.sysext' to the deployed symlink name sidenote on the tests and autobuilder failure: run locally they succeed, e.g.: #> oe-selftest --verbose -r imagefeatures.ImageFeatures.test_image_gen_pkgdbfs changes with v6: tests: restructure to call 'bitbake' only once in the testcase itself (in hopes of solving the autobuilder problem; local test runs succeed) changes with v7: tests: undo the restructuring of done in v6, in favour of explicitly forcing steps: '-c rootfs -f'. since concurrency of the autobuilder, and reusing artifacts/sstate-caching is probably the issue? changes with v8: tests: fixed missing feature=PACKAGE_CLASSES during 'test_image_gen_pkgdbfs' which is now split into three, one for each of the three available packagemanager: ipk, deb, rpm changes with v9: tests: fix singular failure in 'oe-selftest-armhost' which was due to the built image not containing a 'kernel-image...', which the gen-pkgdb sanity check expected, but 'packagegroup-core-boot' instead changes with v10: tests: fix runCmd usage in relation to native-dirs due to which only the use-pkgdbfs-ipk test would fail in a qemu run armhost environment
