I don't have any specific "grub" partition, every Linux install has its
own grub install in its own /boot BTRFS subvolume.

But I of course have only one grub actually installed in the disk MBR,
the one that corresponds to the distro I use most (and for which I redid
« grub-install /dev/sda » last).

As this grub doesn't auto-detect the other distros, I simply chain from
there the other distro's grub.cfg, by having crafted once for all a :


"/etc/grub.d/40_custom" that contains, i.e. :


#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply
type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

menuentry "DebMint Loader (Chained)" {
    configfile (hd0,2)/LMDE/@boot/grub/grub.cfg
}

menuentry "Mint 13 Loader (Chained)" {
    configfile (hd0,2)/MINT/@boot/grub/grub.cfg
}

menuentry "Bodhi Loader (Chained)" {
    configfile (hd0,2)/BODHI/@boot/grub/grub.cfg
}


That's all folks ;-))
