I guess, he isn't. It's what I recommend, too. It's the only way to make sure
the different OSes/distros bootloaders do not interfere with each other.
Well it's not a good recommendation to do what is explicitly not recommended by GRUB
devs. grub-install spits out a warning if you try to do this, by the way. It requires the
user pass --force for it to work. And --force also isn't supported by anaconda for 4-5
Fedora releases now. It can't be used if /boot is on XFS or LVM or md RAID, all of
which lack boot loader padding areas, so fewer configurations are supported. You're
better off using extlinux if you want something that supports installation to a
partition.
The earlier suggestion to have the primary grub.cfg include an entry using configfile to
point to each distribution's grub.cfg is the better way to handle this. Each
distribution updates only their own grub.cfg. And as far as I'm aware, no distribution
ever re-runs grub-install, so the existing bootloader is only going to be
"interfered" with by users reinstalling the bootloader or installing a new OS.
