Some opkg commands print an error during cleanup when the tmp_dir does not exist and an attempt is made to delete it. The error messages are harmless and the opkg commands eventually succeed. When these commands are run and stderr is piped to stdout, the error messages may clobber the stdout and cause unexpected results while parsing the output of the command. Therefore, when parsing the output of a command, do not pipe stderr to stdout. Instead, capture stderr and stdout separately, and upon success, send stderr to bb.note().
