Subject: [PATCH 22/24] tests: update for work in fake dev environment
No write outside of $LVM_TEST_DIR (removed /test access).
Use 'aux prepare_scsi_debug_dev' for automated scsi_debug handling
Properly use "" around shell vars.
Smarter read of PVS values.
Relax requirement to only work with real /dev dir.
