If adding multiple config files to the merge_config.sh script and rust/config is the fist one, then the last config fragment in this file and the first config fragment in the second file wont be set, since there isn't a newline in this file, so those two fragements end up at the same row like: CONFIG_SAMPLE_RUST_PRINT=mCONFIG_FRAGMENT=y And non of those will be enabled when running 'olddefconfig' after. Fixing the issue by adding a newline to the file.
