The problem is not LVM moving /boot close to the end of a hard drive, but that when you have /boot as part of the / partition, instead of giving its own partition, the files in /boot may end up towards the end of the drive. > e.g. If you had created /boot/, /home/, /tmp/, /usr/, /var/, in that > order, you might find that at the end of your manual intervention, it > actually created the partitions in another order, albeit with /boot/ > being the first partition. > > Of course, thanks to how drives fake their number of heads and > cylinders, to accomodate how BIOSs (and IDE?) are still terribly poor at > handling large drives, there's still no guarentee that all of the first > partition is going to be where the BIOS can access it. > The drives internal remapping should have no affect on what the BIOS can access. The BIOS just tells the drive I want this track, head, sector, and it could care less where it really is on the drive. If the partition is the first x blocks on the drive, the BIOS can access it, regardless of the physical location on the drive, as long as the logical h,t,s is in the range the BIOS can handle.
