Re: [PATCH v3 3/3] meta: Move DTB deployment to a separate dtb-files recipe

["'Prusty, Badrikesh' via isar-users" <isar-users@googlegroups.com>]

Hello Anton,

Can we proceed with merging this patch?

Regarding the kernel name issue, I would like to share a suggestions for
consideration. For images that do not require kernel installation and
are intended solely for image generation (e.g., Docker images), the
deploy directory logic could be adapted as follows:

```
# Deploy directory: meta/conf/bitbake.conf
DEPLOY_DIR_IMAGE = "${DEPLOY_DIR}/images/${MACHINE}-${DISTRO}${@ (ker := d.getVar('KERNEL_NAME')) and '-' + ker or '' }"

# For fixing installer image: meta-isar/classes-recipe/installer-add-rootfs.bbclass
INSTALLER_TARGET_KERNEL ??= "${KERNEL_NAME}"
INSTALLER_TARGET_DEPLOY_DIR_IMAGE ??= "${DEPLOY_DIR}/images/${INSTALLER_TARGET_MACHINE}-${INSTALLER_TARGET_DISTRO}${@ (ker := d.getVar('INSTALLER_TARGET_KERNEL')) and '-' + ker or '' }"
```

This ensures that kernel name is included only when populated.

Any thoughts on this?


Many Thanks,
Badrikesh

Hello Badrikesh,

Thanks for good catch.
It looks like the fix will require kernel name of installer target to be
predefined, which can be tricky in some cases.
Will try to think about any other possible solution.
