Bug#801631: Os-prober identifies a Devuan installation as 'unknown Linux distribution'

[David Hare <davidahare@gmail.com>]

Package: os-prober
Version: 1.65
Severity: normal
Tags: patch

When invoking 'update-grub' an installation of Devuan on another 
partition is identified by os-prober as 'unknown Linux distribution'. It 
does have an /etc/devuan_version file. By contrast, os-prober supports 
detection of other OS's (including some Debian derivatives).

Please resolve this for future versions. A simple 3-line patch to 
/usr/lib/os-probes/mounted/90linux-distro (enclosed) has been observed 
to work (by myself only so far).
