The problem you are running into is not something we can fix, unfortunately, or at least not in a full and general way. The problem is that there are certain mount options which are parsed by the mount command (in userspace) and then translated to a mount flag, which is then passed to the mount command as a bitmask, and which is interpreted by the VFS layer before calling the file system. The mount options field in the superblock is parsed by the ext4 file system along with options that were not parsed by the mount binary, passed to the VFS, which then passed it to ext4 file system driver. In theory, we could interpret relatime in ext4 and replicate its effects. For relatime, this is trivial to do. There may be other mount options which are interepted by the mount userspace program, and implemented in the VFS, where this would be much less easy to do. > Other options like noacl, nouser_xattr, are ignored too. This > filesystem is not listed in fstab. This is exactly the same issue.
