Fix it by adding more filter rules to _filter_ro_mount and updating associated .out files to unify the output from both old and new util-linux versions. Signed-off-by: Eryu Guan --- v4 (also passed with both old & new util-linux): - add more comments to explain the output differences between util-linux versions - print out message directly instead of using perl variables - add word "device" to failed ro mount message v3: - document the filtered format in comments - remove legacy sed filter, the perl filter covers the legacy case well - filter out $SCRATCH_DEV/MNT too and use a consistent output - remove the new filter_mount helper in overlay/035 common/filter | 59 +++++++++++++++++++++++++++++++++++++++++++++++---- tests/generic/050 | 8 +++---- tests/generic/050.out | 8 +++---- tests/overlay/035 | 4 ++-- tests/overlay/035.out | 4 ++-- 5 files changed, 67 insertions(+), 16 deletions(-) diff --git a/common/filter b/common/filter index a212c09aa138..9c33efacea6c 100644 --- a/common/filter +++ b/common/filter @@ -397,11 +397,62 @@ _filter_ending_dot() sed -e "s/\.$//" } -# Older mount output referred to "block device" when mounting RO devices -# It's gone in newer versions +# Older mount output referred to "block device" when mounting RO devices.
