+Subject: [PATCH] Remove non-free Agafari fonts
+
+Based on legal analysis, we are removing non-free fonts for now. If we
+can change the license of these fonts, we will return them back.

+Subject: kbd: Legal problems of Agafari fonts
+
+    The data/consolefonts/README.Ethiopic contains a notice:
+    Agafari:
+      Donated by the Ethiopian Science and Technology Commission
+      <ncic@padis.gn.apc.org> or <ncic@telecom.net.et> and may be redistributed
+      for non-commercial use under Unix environments only.
+
+    According to our legal review, it makes impossible to distribute these
+    fonts as part of any commercial products, and even makes it impossible to
+    distribute kbd sources as part of any commercial product services.
+
+    Additionally, it makes the whole kbd package incompatible with GPL, so the
+    COPYING file (created during build of the tarball) cannot declare GPL
+    version 2. It also violates section 6 of GPL (no further restrictions).
+
+    That is why several GNU/Linux distributions exclude Agafari from the
+    release. To be on a safe side, SUSE even decided to repack any source
+    tarballs before putting it to their servers.
+
+    This was probably reported to the former kbd maintainer about 20 years ago,
+    but nothing changed over years.
+
+    That is why I recommend removing Agafari fonts and removing the reference
+    to them from README.Ethiopic. Alternatively, you can ask the Ethiopian
+    Science and Technology Commission for re-licensing.
