Code review comment for lp://qastaging/~psusi/ubuntu/precise/installation-guide/partitions

I'm not saying the documentation is correct in all respects, but you
can't just remove that big chunk of text. GRUB can handle CHS to some
extent; and in any case it isn't just CHS, there are other reasons why
you might need /boot to be near the start of the disk.

No, please don't exaggerate. If it were one in a million I very much
doubt I'd have seen multiple examples of this.

If you want a thoroughly modern example, >2TB disks are becoming common,
but in discussions with BIOS people nobody is able to tell me with any
confidence that the weakly-tested support for 64-bit reads using BIOS
calls actually works on a plurality of systems, and thus it's quite
possible that /boot needs to be in the first 2TB of the disk if you're
using GPT with BIOS (which otherwise ought to work fine in most cases)
in order to avoid lurking unreliability. While the reasoning is quite
different from that in the guide at the moment, the ultimate advice is
essentially the same.
