The patch below fixes it for me but it wasn't immediately obvious how to best return info to the user (ie print messages that make sense here - "echo" seems to be supressed in common/rc and notrun exits and logs it to a file but not to the screen in this case) sfrench@ubuntu:~/xfstests$ git diff -a diff --git a/common/rc b/common/rc index d5e3aff..866244b 100644 --- a/common/rc +++ b/common/rc @@ -555,6 +555,9 @@ _mkfs_dev() _scratch_cleanup_files() { _scratch_mount + if !
