Vendor snapshot can be captured with "m dist vendor-snapshot". With vendor snapshot and vndk snapshot, older version of /vendor and newer version of /system will be able to be built together by setting BOARD_VNDK_VERSION to past vendor's version. Only vendor modules under AOSP are to be captured. In detail, modules under following directories are ignored: - device/ - vendor/ - hardware/, except for interfaces/, libhardware/, libhardware_legacy/, and ril/ Test modules (cc_test, etc.) and sanitized modules are also ignored. Bug: 65377115 Test: m dist vendor-snapshot Change-Id: If7a2f6de7f36deee936930c0ccf7c47c4a0cebf6
