Bug#983506: grub2-common: grub-install doesn't install files to /boot/grub/i386-pc

[Vratislav Blazek]

Package: grub2-common
Version: 2.02+dfsg1-20+deb10u3
Severity: important

Dear Maintainer,

   * We use grub-install while preparing a new system in chrooted environment.
   
   * After upgrade from 2.02+dfsg1-20+deb10u2 to 2.02+dfsg1-20+deb10u3, grub-install stopped to install files in /boot/grub/i386-pc dir.
   
   * Command we use:
   
       chroot "${INSTALL_DIR}" grub-install /tmp/dummy_nonexistent
   
   * Working workaround - copy files explicitly:
   
       chroot "${INSTALL_DIR}" "mkdir -p /boot/grub/i386-pc/" || die
       chroot "${INSTALL_DIR}" "cp /usr/lib/grub/i386-pc/*.mod /boot/grub/i386-pc/" || die
       chroot "${INSTALL_DIR}" "cp /usr/lib/grub/i386-pc/*.lst /boot/grub/i386-pc/" || die
       chroot "${INSTALL_DIR}" "cp /usr/lib/grub/i386-pc/efiemu*.o /boot/grub/i386-pc/" || die
       chroot "${INSTALL_DIR}" "cp /usr/lib/grub/i386-pc/modinfo.sh /boot/grub/i386-pc/" || die
