Yes. That is expected to work. Please try defining the following
env variable. It will give us some debugging output to work with.

export GLUSTERFS_BOOSTER_LOG=<file-pathname>

If this does not help, lets test again with 2.0.7. The rc1
should be out later today. In the past few days we've fixed a few
causes of crash in booster.

Do you mean the scripts contained commands with LD_PRELOADed
booster? Or were you trying to run bash with LD_PRELOADed booster?

The second scenario will not work at this point.
