Did more discovery on this, but not confident in what I found. It seems that
sai.mk contains the important bits of selecting an image to download from a bucket at
https://sonicstorage.blob.core.windows.net/public/sai/sai-broadcom. For instance, libsaibcm_13.2.0.7_amd64.deb. Still discovering nuances like what xgs and dnx variants are.
The last commits to the sonic-platforms-modules-accton directory was on 31-Oct-2023 by Jostar Wang. It appears this commit updates the build to Bookworm and the branch was propagated to 202505. So with the updates to LIBSAIBCM_XGS_VERSION and LIBSAIBCM_DNX_VERSION, does that imply that the build on 202505 branch ought to work on Bookworm?
Any thoughts appreciated!!
