No, we don't need to prepend `"/"` to the path because every string in the
`missingCgroup` is guaranteed to represent an absolute path. These paths are
constructed by using `path::join`, which automatically adds `"/"` between
arguments:
```
currentCgroup = path::join(currentCgroup, *it);
```
Previously, `cgroup` variable could refer to a relative path, so it was
necessary to prepend `"/"`.
