I had a talk about this with Colin at debconf, and it seems that there aren't
that many cases left where grub-mount is not available. It might be best to
disable the probing (by default) on all architectures where grub-mount is
available.
On the architectures where grub-mount isn't available (currently mips, arm*
and s390*), the question is whether it makes sense to try to randomly mount
other filesystems by default in the hope of finding another OS installation,
knowing this might break something.
Cheers,
Ivo
