 %changelog
+* Thu Aug 18 2022 Tony Camuso <tcamuso@redhat.com> - 1:1.10.5-2
+- The install scriptlet in %post was choosing the first grub.cfg
+  file it encountered, which was /boot/efi/EFI/redhat/grub.cfg.
+  This is a stub that defines grub boot disk UUID necessary for
+  proper grubenv setup, and it must not be overwritten or changed.
+  Modify the scriptlet to target /boot/grub2/grub.cfg
+  Additionally, remove any wrongly created /boot/grub2/x86_64-efi
+  directory and recreate the correct /boot/efi/EFI/redhat/grub.cfg
+  stub file.
+  Added a %postun section to cleanup when removing tboot with
+  dnf erase.
+  Thanks to Lenny Szubowicz for the bash code to recreate the
+  /boot/efi/EFI/redhat/grub.cfg stub file.
+  Resolves: rhbz#2112236
