There's no support for this in Linux (although I'm hoping to change that) but it'd be nice if blkid could at least recognize it. So I thought you might be interested in the filesystem signature for ReFS, which appears to be in the first 8 bytes: 00000000 00 00 00 52 65 46 53 00 00 00 00 00 00 00 00 00 |...ReFS.........| 00000010 46 53 52 53 00 02 c8 6b 00 00 4e 01 00 00 00 00 |FSRS...k..N.....| 00000020 00 02 00 00 80 00 00 00 01 01 00 00 00 00 00 00 |................| 00000030 00 00 00 00 00 00 00 00 95 0a d9 2c 1b d9 2c 02 |...........,..,.| 00000040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| There is nothing else that looks even vaguely like a superblock within the first few megabytes, so I'd go with those first 8 bytes for now.
