Keep the historical auto-mount behavior as the first attempt when the user did not request a filesystem type. If that mount fails on Linux, detect the filesystem with blkid and retry only for FAT-family types that minimal mount implementations may not auto-probe. Leave explicit filesystem types and NTFS kernel-driver resolution unchanged.
