HFS/HFS+ is also used by PowerPC users on PowerMac hardware for both
exchanging data between MacOS and Linux as well as for booting Linux
using GRUB with a HFS/HFS+ /boot partition.
Debian's grub-installer creates an HFS partition from which GRUB loads
the kernel and the initrd [1]. In order to be able to update kernel and
initrd, the running Linux system needs to be able to read/write HFS/HFS+
partitions which is used for the /boot partition.
