From: Christian Brauner <christian.brauner@xxxxxxxxxx> We're not using the shortopts anywhere anyway and shouldn't encourage using shortopts. It's much more descriptive to see: $here/src/idmapped-mounts/idmapped-mounts \ --test-btrfs \ --device "$TEST_DEV" \ --mountpoint "$TEST_DIR" \ --scratch-device "$SCRATCH_DEV" \ --scratch-mountpoint "$SCRATCH_MNT" --fstype "$FSTYP" in a test than it is to see: $here/src/idmapped-mounts/idmapped-mounts \ -b -d "$TEST_DEV" \ -m "$TEST_DIR" \ -s "$SCRATCH_DEV" \ -a "$SCRATCH_MNT" \ -f "$FSTYP" In the second case one has to go consult the source code to make sure that the correct option is passed. In the first case one can just see it directly.
