The thing is - I don't want to deviate the code too much from what's doing
on the other architectures. I don't necessarily disagree with you, but I just
want to go along with the other architectures for the time being.

However, if you're really concerned about the issue, I think we should discuss
this in a separate thread and also involve the debian-boot mailing list so
that we can find a common solution for all architectures.

We can still address this once the other stuff works. You definitely have a
point though that there can be cases where the current code will most likely

Maybe it's a good idea to perform some tests with such setups on x86 (e.g.
having MBR partitioning and then booting the machine in EFI mode and keeping
the MBR setup) and observe what debian-installer does.

PS: I wrote "MFT" in my previous mail. I meant MBR, of course. MFT is part of
