Hello,
I am trying to setup a shared directory, that is a directory where all content is shared among selected local users so that everyone can create, move and delete as needed.
I followed this guide first How to create a Shared Folder between two Local User in Linux? - GeeksforGeeks (there are many identical guides on other websites) but it became immediately clear that any file copied from other directories to the shared directory would keep the original permissions and ownership.
So after reading more on the subject I came to the conclusion that ACL is needed to make sure that all selected users are actually able to operate on files and directories (this may be wrong in itself, comments welcome of course).
After setting up the needed setfacl commands
Riepilogo
sudo setfacl -m g:sharegroup:rwx /home/shared
I am getting the same results as before, so I checked and apparently my BTRFS volume doesn’t have ACL enabled? This is the output from mount:

Is ACL really disabled? How can I enable it if needed? Thank you
