That is a good question but in this case there is a human looking at the
rabbitmqctl status who maybe is not even interested in the free space
info (which can be easily obtained elsewhere) but can see no rabbitmq
information on account of this bug.

So I don't know of any APP1 being affected by this result. Nevertheless
I think It would be nice that the versions for focal and jammy return
the same value when this error happens instead of using two different
ones. I'll upload a new focal debdiff that also returns unknown to be
consistent.

Title:
  Failure to get free disk space breaks "rabbitmqctl status" command

Status in rabbitmq-server source package in Focal:
  In Progress
Status in rabbitmq-server source package in Jammy:

Status in rabbitmq-server source package in Kinetic:

Bug description:
  [Impact]

  When for some reason the df command fails to get the disk free space
  (for example timeout on a heavily loaded system) the result is a
  harcoded value of "unknown". As this is not a valid number this
  generates arithmetic errors when the "rabbitmqctl status" command is
  run and tries to divide that value to convert it to another unit.

  This has been fixed upstream here:
  https://github.com/rabbitmq/rabbitmq-server/pull/4897

  [Test Plan]

  The df command can be linked to another file that just waits for a few
  minutes to force a timeout for example: [detailed steps in comment
  #5].

  #!/bin/bash
  sleep 5m

  After the timeout occurs the "rabbitmqctl status" returns an error
  with the unpatched version. After the patch it shows all the
  information and displays unknown in the free space line.

  [Where problems could occur]

  The patch just changes the display of information, it should not break
  anything in the core operations of the package
