Test Case: Basic Mount and Unmount

Test ID: TC001-mount-basic

Objective

Verify that the exact G1 KLD mounts a valid image read-only, exposes source data exactly, and unmounts cleanly.

Fixture

Use images/compact.erofs and source/compact/root.txt generated by tests/prepare_g1_fixtures.sh. Follow tests/G1-MANUAL-SETUP.md and record the image, source, and KLD SHA256 values.

Procedure

image=/tmp/repo22-g1/images/compact.erofs
source=/tmp/repo22-g1/source/compact/root.txt
mnt=/mnt/repo22-g1-001
md=$(mdconfig -a -t vnode -f "$image")
mkdir -p "$mnt"
kldstat | grep -i erofs
mount -t erofs -o ro "/dev/$md" "$mnt"
mount -p | awk -v p="$mnt" '$2 == p'
cmp "$source" "$mnt/root.txt"
sha256 "$source" "$mnt/root.txt"
./statfs_probe "$mnt"
umount "$mnt"
mdconfig -d -u "${md#md}"
rmdir "$mnt"

Expected Results

• Mount, cmp, statfs_probe, unmount, and detach all return zero.
• The mount entry is erofs and read-only; both file hashes are identical.
• Cleanup leaves neither this mount point nor its md provider.
