Comment 1 for bug 1543029

Looking at the fix for bug 1511451, I see that both xtrabackup and innobackupex fail with error if --defaults-file isn't first argument on the command line.

Here is the test case for reference

run_cmd_expect_failure ${IB_BIN} \
 --datadir=$topdir/data \
 --defaults-file=$MYSQLD_VARDIR/my.cnf \
 $topdir/backup

run_cmd_expect_failure ${XB_BIN} \
 --datadir=$topdir/data \
 --defaults-file=$MYSQLD_VARDIR/my.cnf \
 --backup \
 --target-dir=$topdir/backup

run_cmd_expect_failure ${IB_BIN} \
 --datadir=$topdir/data \
 --defaults-extra-file=$MYSQLD_VARDIR/my.cnf \
 $topdir/backup

run_cmd_expect_failure ${XB_BIN} \
 --datadir=$topdir/data \
 --defaults-extra-file=$MYSQLD_VARDIR/my.cnf \
 --backup \
 --target-dir=$topdir/backup

if [ `grep -c 'must be specified first' $OUTFILE` != '4' ] ; then
 die 'Error message mush be repeated 4 times'
fi
