Description

By default, when racer is run on a singe node it will create a second mount point at /mnt/lustre2 but it doesn't actually use that second mount point to do any operations. Although lustre/tests/racer/racer.sh will be invoked twice, once with argument /mnt/lustre/racer and once with /mnt/lustre2/racer, it uses $DIR when set rather than $1:

#!/bin/bash                                                                                                                                             
#set -x
