   Users might not create a fs backend with a non-existent root on purpose. 
   
   For instance I once tested `oli cat` by reading a local file and I mistyped the path, like `oli cat /tmp/not-exist/foo`, and then a dir named `non-exist` was created under `/tmp`. 
   
   Another case is that if I run the test [test_parse_fs_location](https://github.com/apache/incubator-opendal/blob/0069c92af7f6a4380653caa01276776031ef03e9/bin/oli/src/config/mod.rs#L304-L312) locally, a dir named `foo/bar` will be created under PWD, which supprises me as no read/write operation is actually performed.
