Assumpte: [DNG] os-prober detects Devuan as "Unknown Linux Distribution"
Don't know if there is an "official" plan to sort this. It is an
annoyance that os-prober (normally run at update-grub) detects my
(bootstrap-installed) Devuan as "Unknown Linux Distribution" then that's
what you get in grub menu.

This is fixed here by adding after line 23 of
/usr/lib/os-probes/mounted/90linux-distro :

    elif [ -e "$dir/etc/devuan_version" ]; then
        short="Devuan"
        long="$(printf "Devuan GNU/Linux (%s)\n" "$(cat 
"$dir/etc/devuan_version")")"


In whatever OS is your "master grub". If that is your Devuan system, or
you chainload it, you need also lsb-release installed OR edit
/etc/default/grub else main system shows as "Debian GNU/Linux".

Afterwards:
