Public bug reported:
Upgraded a number of servers (more than 30) from various LTS versions to LTS
20.04
In each case that uses mdadm, all links for mdadm in /etc/rcX.d/*mdadm* are
broken links.
Every upgraded server using mdadm matches the issue exactly, but choosing one
server:
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.04
DISTRIB_CODENAME=focal
DISTRIB_DESCRIPTION="Ubuntu 20.04.2 LTS"
mdadm:
Installed: 4.1-5ubuntu1.2
Easiest way to see the issue is to type:
# ls -lasd `find /etc | grep mdadm`

../init.d/mdadm-waitidle
Since init.d/mdadm and init.d/mdadm-waitidle don't exist, all the
/etc/rcX.d/*mdadm* links are broken links
- and in a colour terminal are all highlighted distinctly
All systems boot successfully, so I'm not sure if it is simply a cleanup
issue during upgrade from 18.04 to 20.04, or if the files should exist?
However, a previous version desktop, which is:
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.2 LTS"
has init.d/mdadm and init.d/mdadm-waitidle thus they aren't broken links
** Affects: mdadm (Ubuntu)
Importance: Undecided
Status: New
** Package changed: linux (Ubuntu) => mdadm (Ubuntu)
