sota_sanity.bbclass: introduce sota_check_boolean_variable

2020-05-11T17:53:55+00:00

The current sanity check are too strict for some boolean variables, introduce sota_check_boolean_variable to allow a boolean value to be set like yes/y/true/t/1 or no/n/false/f/0. Also change to use oe.types.boolean to check their values. Signed-off-by: Ming Liu

image_types_ota: use named reference

2020-05-07T21:06:55+00:00

Use named reference when deploying the device tree. This makes sure that this reference will end up in the deployments .origin file, which will be visible by the user in ostree admin status. This reference will also be used when running ostree admin upgrade. This is not really required when using aktualizr, but can be useful during test/debugging when using pure OSTree updates. Make sure to make ${OSTREE_REPO} accessible via http and add a remote on the device called ${OSTREE_OSNAME} pointing to the http exposed archive OSTree. With that ostree admin upgrade should work. Note: We could use the name reference in ostree pull-local already, but this is potentially racy if multiple builds are committing to the same branch. Use the OSTree commit hash to get the actual commit and recreate a local reference to this commit. This makes absolutely sure that we use the same OSTree commit this bitbake execution committed during the do_image_ostreecommit task. Signed-off-by: Stefan Agner

image_types_ostree/ota: use hash from ostree commit

2020-05-07T21:06:55+00:00

Relying on a OSTree branch reference has been problematic in the past and addressed by adding more attributes to it in commit 202a8c70ba8c ("image_types_ostree: Add a unique ref to fix simultaneous bitbaking."). However, depening on what kind of OpenEmbedded builds are running in parallel, even more attributes would need to be taken into account. Instead of relying on a reference, store the exact ostree commit hash in a manifest file and reuse it in the do_image_ota deploy task. This guarantees that the correct reference gets picked even when two builds with the exact same machine/image name run in parallel. Note: This gets rid of the second branch name again. If the branch name with image name is preferred, the variable OSTREE_BRANCHNAME can be used: OSTREE_BRANCHNAME = "${SOTA_HARDWARE_ID}-${IMAGE_BASENAME}" Signed-off-by: Stefan Agner

image_types_ostree/ota: move home physically to /var/rootdirs/home

2020-04-27T07:42:22+00:00

Instead of using the double indirection mode /home -> /var/rootdirs/home -> /sysroot/home move the home directory physically into /var/rootdirs. This allows to use the --modern flag when initializing the file system. The "old" style is still supported, and does make sense in case the home directories need to be shared between multiple deployments. Since multiple deployments is not a use case in meta-updater use the /var approach. See also: https://github.com/ostreedev/ostree/issues/2085. The modern flag also gets rid of dev, proc, root, run, sys and tmp. All of them have been empty and unused. Note: This change cannot be pushed through updates as this is an initial deployment setting. Only devices provisioned with images built with this change applied will use the new layout. Updates will continue to work on both systems as the symlink from the deployment stays the same (first indirection is still /home -> /var/rootdirs/home). Signed-off-by: Stefan Agner

image_types_ostree/ota: do not commit homes to the OSTree

2020-04-27T07:42:22+00:00

The home directory currently are commited to the OSTree, presumably to then use it for the deployment. However, we do have access to the original rootfs in the OSTree deployment tasks (do_image_ota) hence transferring the files "via OSTree" is not necessary. We do already carry over some files from the original OE rootfs to /var/sota. Follow this approach for /var/local and /home as well. The home will still be stored in the sysroot as documented in https://ostree.readthedocs.io/en/latest/manual/adapting-existing/. Signed-off-by: Stefan Agner

image_types_ostree: use hardlink tree

2020-04-27T07:42:22+00:00

Instead of copying the files to be commited to the ostree just use a hardlink tree. This improves performance and wasts less diskspace. When using this method the root directory has already the correct permission bits set. Also get rid of the unnecessary sync. This halfs the execution time of the do_image_ostree tasks in my measurments. Signed-off-by: Stefan Agner

image_types_ostree: drop unnecessary tmp handling

2020-04-27T07:42:22+00:00

The current code clears tmp and then creates a symlink inside it to /sysroot/tmp: tmp └── tmp -> sysroot/tmp This is likely a mistake and the root tmp should have pointed to sysroot/tmp. However, since /tmp is mounted as a tmpfs anyways, we can get rid of all this logic. Signed-off-by: Stefan Agner

image_types_ota: export OSTREE_BOOT_PARTITION when needed

2020-04-27T07:42:22+00:00

The environment variable OSTREE_BOOT_PARTITION is only used when using GRUB. Move the export into the if statement. Also add a comment why manually adding /boot/loader{.0} directory is necessary. Signed-off-by: Stefan Agner
