[Bug 2012684] Re: convert: gsfonts are missing after 8:6.9.10.23+dfsg-2.1ubuntu11.6

This is because `/etc/` is now prohibited in the default policy file. I
don't know why that change was made as part of
https://bugs.launchpad.net/ubuntu/+source/imagemagick/+bug/2004580, it's
definitely wrong.

Title:
  convert: gsfonts are missing after 8:6.9.10.23+dfsg-2.1ubuntu11.6

Status in imagemagick package in Ubuntu:
  New

Bug description:
  Background
  ----------

  Our builds have started failing generating images with imagemagick as
  of around 2023-03-22 TZ +1100

  All issues seen on 20.04 - definitely failing with version
  8:6.9.10.23+dfsg-2.1ubuntu11.6

  Package version details below

  Issue
  -----

  This generation command was working in clean-room 20.04 builds up to
  this point in time

  convert -background black -fill white -size 50x50 -gravity Center
  -font "fixed" -pointsize 48 label:01 text_01.png

  Now it fails with

  $ convert -background black -fill white -size 50x50 -gravity Center -font "fixed" -pointsize 48 label:01 text_01.png
  convert-im6.q16: unable to read font `fixed' @ error/annotate.c/RenderFreetype/1338.
  convert-im6.q16: no images defined `text_01.png' @ error/convert.c/ConvertImageCommand/3258.

  Investigation
  -------------

  Issue occurs on version "8:6.9.10.23+dfsg-2.1ubuntu11.6"

  apt is refusing to install the ".4" (probably last known good) or ".5"
  versions - saying they are unavailable.  I've reverted back to version
  "8:6.9.10.23+dfsg-2.1ubuntu11" for the comparison.

  I can see the difference with "convert -list font"

  In 1ubuntu11 (works) I see "fixed" in the list

    Font: fixed
      family: Helvetica
      style: Normal
      stretch: Normal
      weight: 400
      glyphs: /usr/share/fonts/type1/gsfonts/n019003l.pfb

  in 1ubuntu11.6 it is not present.

  Using the command "convert -list font" under strace I see that ghostscript fonts are no longer being parsed.  The outputs are identical until:

  In 1ubuntu11 (works) I see:

  ...

  In 1ubuntu11.6 I see at the same point - then the output continuing the same as 1ubuntu11 after:

  Has someone changed the --configure line?
