## Description

```
guix shell --root
```

 Let's benchmark and test these options to see if it helps the speed/times
 with building a new container.

```
-r, --root=FILE        make FILE a symlink to the result, and register it
                       as a garbage collector root
```                      

```

01/27/2022 | 06:48:17 PM  lfam: I mean the --gc-keep-[...] options
