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.
