OK if the general policy will be that for existing systems there is no
need to upgrade grub in this situation that will be great - and if
grub-legacy is in the AUR but no further development or changes takes
place then that would satisfy me and there would be presumably no need
to install the grub-legacy package from AUR? Just continue to update
using pacman -Syu?

A further question then arises - let's say there is a system on which
arch is not yet running and a new arch install needs to be done - but
that the disk is pre-partitioned and has perhaps Windows XP or Windows
7 that the user would like to preserve with a dual boot system - and
which perhaps has an OEM (HP) recovery partition between the MBR and
the NTFS Windows partition with a post-MBR gap of 64 sectors. When
installing arch when the default is grub2 - would it then need a
larger post-MBR gap to achieve a successful (and bootable) install?
(This is for the presumption that it has BIOS and MBR partitioning
only - and again no GPT or UEFI) - or would an install along the lines
that most people have been used to doing with existing install media
work perfectly well?
