system_profiler now answers SPHardwareDataType and SPSoftwareDataType (and lists them in -listDataTypes). Model, serial number, platform UUID and provisioning UDID come from IOKit's IOPlatformExpertDevice via ioreg; CPU, cache and memory from sysctl; the OS version from sw_vers and uname. A field the guest does not provide is left out. #61 instead read a separate darling-smbios.conf written by a new generator (gen-darling-smbios.py), with hardcoded fallbacks (an Intel Core i9, macOS 14.7, SIP enabled). iokitd reads darling-platform.plist, so system_profiler and IOKit could report different serials and models on the same prefix, and the generator overwrote identities imported with configure-darling-platform.py. Reading the guest's own APIs keeps a single source of truth: configure-darling-platform.py remains the only way to set or provision an identity, and it is still never run by install or launch. tests/test_system_profiler.py runs the script under sh with stub guest commands and runs in CI. Split from #61. Co-authored-by: DevWebeloper <[email protected]> Co-Authored-By: Claude Opus 5.5 <[email protected]>
