Thanks for digging this up. I wasn't aware of this particular issue before
and I agree, this needs to be addressed. I hope that I didn't cause too
many DOS partitions to be misdetected. Sorry for the inconvenience if I
did. The Atari partition table code has been working great for
Debian/m68k so
far though.
I have seen at least one or two reports of Ubuntu users getting false
positives, and then I saw the bug report on the upstream parted bug
tracker the other day where someone claimed to have found a logical
error that caused atari_probe to return true when it shouldn't. I
finally realized it was not an error ( at least I think not ).
According to the documentation, p.43 [1], I think offset $01 should always
contain either "GEM", "BGM" or "XGM". They don't seem to be optional.
I guess adding those to atari_probe() should help improve the detection
quite a bit. But I would have to test that first.
I think I will at least move atari to be probed after all other labels
have failed.
This sounds like a reasonable thing to do until I have worked out
a patch to improve atari_probe().
