**Tell us about your request**
What do you want us to build?

When using setuid, setgid, or stickybit permisisons on a folder, you will get this error:

```
CreateFolder: [ ERROR ] Encountered permissions error given permission '2750' does not lie between 0 and 777
```

I have not tested with a file but I am willing to bet the same issue will apply.

The docs show the permissions default value as `0777` which leads one to believe `2750` would be supported. Either update the docs to show only `777` or allow the use of setuid, setgid, and stickybit.

**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
I am trying to set setgid permissions for a folder in Linux.

**Are you currently working around this issue?**
How are you currently solving this problem?

I create the folder using `CreateFolder` then run `ExecuteBash` to set the proper permissions. I may stop using `CreateFolder` due to this limitation.

**Additional context**
Anything else we should know?

This should also be tested with files. I suspect this to be the same issue with them.

Start by tracing the CreateFolder permission validation and compare it with the documented default of 0777; the issue also names ExecuteBash as the current workaround. Check whether the same validation affects files, then verify that setuid, setgid, and sticky-bit permissions are either accepted or explicitly documented as unsupported.
