@2T2@mstdn.starnix.network No FAT file systems I know of have owners or access permissions. The only attributes they have are: "read-only", "system", "hidden" and "archived". And you need some vfat tool to set those I think. Even if you manage to set UNIX-like permissions you will lose those on unmount. I'm not sure about ExFAT though, maybe it can handle some extended attributes 🤷
