Just a small nitpick:

  awk '/^md/ {printf "/dev/"$1"\n"}' /proc/mdstat

Hi,

...or little bit more easy(?):

[ -f /proc/mdstat ] && sed -e 's,^\(md[0-9]\+\).*$,/dev/\1,p;d' /proc/mdstat

Dear Maintainer,

   * What led up to the situation?
I have Fedora installed on /dev/md5(RAID1) but update-grub / os-prober didn't found it.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Implementing the patch from this bugreport was effective.

   * What was the outcome of this action?
Linux on md device could not be started.

   * What outcome did you expect instead?
Correct detection and starting of other Distribution on md.

BTW:
The following System Information was not correctly detected or the wiki is outdated.
As described on https://wiki.debian.org/AptPreferences I have created /etc/apt/preferences:

Dear Manitainer,

Please consider applying the patch which helps a lot with maintaining
debian machines with root on md raid when rebuilding grub configuration.

Thanks a lot,

Pavel Hofman.

The problem still exists in os-prober 1.79, and I've confirmed that the
patch still applies and solves the problem. Could this (or an
equivalent) be applied for the next version?
