Bug#919813: comparison with earlier release

[Hendrik Boom <hendrik@topoi.pooq.com>]

Just for comparison, on Devuan ascii (stretch wirhout systend), I get:

root@midwinter:/home/hendrik# os-prober
File descriptor 8 (socket:[13898]) leaked on lvs invocation. Parent PID 2831: /bin/sh
File descriptor 9 (socket:[13899]) leaked on lvs invocation. Parent PID 2831: /bin/sh
File descriptor 10 (socket:[16454]) leaked on lvs invocation. Parent PID 2831: /bin/sh
File descriptor 11 (socket:[16455]) leaked on lvs invocation. Parent PID 2831: /bin/sh
File descriptor 18 (socket:[13991]) leaked on lvs invocation. Parent PID 2831: /bin/sh
/dev/sda6:Debian GNU/Linux buster/sid:Debian:linux
root@midwinter:/home/hendrik# 

Here it also does not recognise the OS it runs on, but it *does* recognise
Debian.

Could the problem be that it is does not recognise
  (a) its own OS, nor
  (b) any OS those root partition in on an LVM volume, even if its /boot
      is on a primary partition?
