I would have another suggestion then; how about a scoring system?

Probes would be given OPTIONAL scoring system, let's say in percents, eg. in
case of fat, lack of magic would make it lose 20%; some other filesystem would
return just 0 or 100% hit (ie. just like it is now). Then the probe with
greatest score wins.

I understand this design is for working with semibroken partitions, and I fear
it won't be welcome warmly; but I still got to propose it:)

I am willing to code it, I've written about ten probes for my own detection
system until I noticed libvolumeid, but I want approval of design first.

Thanks in advance
