Description

Looking into test logs of sanityn test 93 we can see it's trying to call some unknown command in some unclear circumstances.

I don't see anything obviously wrong though.

this appears to be only happening in ldiskfs-dne situation for me but I am not sure if it's ldiskfs or DNE that's the requirement.
