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
