The reasoning was that if users use `setup-disk /mnt` the user will
also know how to install the bootloader. There are just too many things
that can go wrong is setup-disk tries to do it, so I never bothered to
do anything about it.

DEFAULT_DISK !=3D boot disk.

exactly, and we dont want setup-disk to remove the other OSes in case
of dualbooting. And we dont want the script to start try figuring out
whatever bootloader is used from before or how to also boot windows etc.

Better let user install boot loader.

currently the setup-disk uses syslinux for BIOS boot and grub for UEFI. I'm=
 not sure the code is there for install grub in BIOS mode.

I thiknk setup script also works for ppc64le, but to be honest, I don't
know.
