In order to support all in-scope SPDX data within a single JSON-LD file for SPDX 3.0.1, Yocto's SBOM: - In native/target/nativesdk recipe, created spdxid-hash symlink for each element to point to the JSON-LD file that contains element details; - In image recipe, use spdxid-hash symlink to collect element details from varies of JSON-LD files While SPDX_INCLUDE_SOURCES = "1", it adds sources to JSON-LD file and create 2N+ spdxid-hash symlinks for N source files. (N for software_File, N for hasDeclaredLicense's Relationship) For large numbers of source files, adding an extra symlink -> real file will occupy one more inode (per file), which will need a slot in the OS's inode cache. In this situation, disk performance is slow and inode is used up quickly While using function add_package_files to add source files to JSON-LD file, the spdxid-hash symlinks for source files point to the same JSON-LD file, then according to the format of spdxId - spdxId of souce file: http://spdx.org/spdxdocs/shadow-10e66933-65cf-5a2d-9a1d-99b12a405441/0838759b8d71923d250a0813dda7356ffd309576115bbf8ed7e266cf4aed86a5/sourcefile/1 Remove the count number ('/1') from spdxId suffix, then all source files in one recipe will share one spdxid-hash symlink.
