As preparation step for configuring test/scratch base fs for overlay tests: - Rename OVERLAY_LOWER/UPPER/WORK_DIR => OVL_LOWER/UPPER/WORK because we want to use OVL_ prefix for all base fs vars - Prepend "ovl-" prefix to lower/upper/work path values to isolate the overlay test dirs when running on a base fs that is also used to run non overlay tests - Make those vars values constant, because lower/upper/work directory names are an internal test detail which should not concern the user and because we wish to simplify and document the overlay tests setup Signed-off-by: Amir Goldstein <amir73il@gmail.com> --- common/config | 8 +++++--- common/rc | 19 +++++++++++++------ tests/overlay/001 | 2 +- tests/overlay/002 | 2 +- tests/overlay/003 | 2 +- tests/overlay/004 | 4 ++-- tests/overlay/006 | 10 +++++----- tests/overlay/008 | 8 ++++---- tests/overlay/009 | 2 +- tests/overlay/010 | 8 ++++---- tests/overlay/011 | 4 ++-- tests/overlay/012 | 4 ++-- tests/overlay/013 | 4 ++-- tests/overlay/015 | 2 +- tests/overlay/016 | 2 +- tests/overlay/017 | 2 +- tests/overlay/018 | 2 +- tests/overlay/019 | 2 +- tests/overlay/020 | 2 +- tests/overlay/021 | 2 +- 20 files changed, 50 insertions(+), 41 deletions(-)
