# Test Case: List the FreeBSD system namespace

**Test ID**: TC072-shared-system-xattr-list
**Fixture**: `basic.erofs`

## Objective

Verify that trusted, security, and POSIX ACL indexes are listed only through
FreeBSD namespace `system` with their ABI names.

## Manual steps

```sh
lsextattr system /mnt/repo22-g4/trusted-shared-a
lsextattr system /mnt/repo22-g4/security-shared-a
lsextattr system /mnt/repo22-g4/acl-unordered
lsextattr user /mnt/repo22-g4/trusted-shared-a
stat -f '%HT %Sp' /mnt/repo22-g4/trusted-shared-a \
  /mnt/repo22-g4/security-shared-a /mnt/repo22-g4/acl-unordered
```

## Expected results

The three system lists contain `trusted.config`, `security.selinux`, and
`posix_acl_access`, respectively. The trusted file's user list is empty.
Unmount and detach.
