 ### 3. Mount Issues
 
 **Container mount notes:**
-- Only mounts directories, not individual files
-- `-v` syntax may NOT support `:ro` suffix - use `--mount` for readonly:
+- Docker supports both `-v` and `--mount` syntax
+- Use `:ro` suffix for readonly mounts:
   ```bash
-  # Readonly: use --mount
-  --mount "type=bind,source=/path,target=/container/path,readonly"
+  # Readonly
+  -v /path:/container/path:ro
 
-  # Read-write: use -v
+  # Read-write
   -v /path:/container/path
   ```
 
 To check what's mounted inside a container:
 ```bash
-container run --rm --entrypoint /bin/bash nanoclaw-agent:latest -c 'ls -la /workspace/'
