Not sure if this is done by design or not, but when running the single node test from within the lustre source tree the installed binaries are used by default; not the binaries in the lustre tree.

For example, running sanity.sh will pick up /usr/bin/lfs and use that binary if it exists (or another lfs found in $PATH I would assume) instead of $LUSTRE/lustre/utils/lfs.

Personally, I find this a bit confusing and frustrating at times. Say, I am working on the lfs command. If I make a change, recompile and run sanity.sh; this new patched version will not be used if there is a version that is already installed. It takes manual intervention to get the test to use my patched version (i.e. running 'export LFS=$LUSTRE/lustre/utils/lfs').

Is this by design?
