I’m setting up a system that will be shared by multiple users.
I have, using acl’s. etc. configured a shared directory such that when files or directories are created the group has rw privilege by default.
If I create a file or folder from a file browser, command line etc. it gets created with rw permissions for the group.
If I open a new session from ardour5 in the same directory, the ardour folders and files get the correct group, but get read only.
