Well that's what I do have here.

Actually looking into util-linux code it says that th the optional
fields are terminated with " - ", see:

https://git.kernel.org/pub/scm/utils/util-linux/util-linux.git/tree/libmount/src/tab_parse.c#n177

So I guess the safest option would be:

* Match the line by major:minor as you do
* Then strstr() for " - " should land us directly to field (8)
