grub2 os-prober wrong on MBR Mac boot

[tz]

Binary package hint: os-prober

On my HP Mini (hackintosh), "os-prober" constructs a complex entry with dozens of lines that FAILS TO BOOT macosx. the partition uses the chameleon bootloader.

The following entry works, though some of the entries might be extraneous (other than the final one):
(the hfs+ partition is on /dev/sda3)

menuentry "Hackintosh" {
 insmod hfsplus
 set root=(hd0,3)
 search --no-floppy --fs-uuid --set xxxxxxxxxx (blkid's returned value)
 parttool (hd0,3) boot+
 drivemap -s (hd0) ${root}
 chainloader /usr/standalone/i386/chain0
}

So first, if whatever mechanism is NOT going to boot macosx, don't create the (very long, and duplicated for 32 and 64 bit) menu entries.

And the chalinloads work for this and DOS.
