If you are using LVM for / and /home, then you need a separate partition
for /boot as this cannot be in a logical volume.

If you want several Linux systems available from the same grub menu,
then having a common /boot and separate partitions for / can be an

Historically, I think there were issues with boot loader not being able
to find boot images that were too far away from the boot record, and so
a separate boot partition position close to the start for the disk was
required. I suspect this is no longer the case with modern hardware.

If you only ever want one operating system on the disk, then it's
