This was lost when code was refactored. Patch restores previous behavior. It is still not clear whether this is the right one. Due to the way we detect DM abstraction, partitions on DM are skipped, we fall through to generic detection which ends up in assuming parent device is BIOS disk. It is useful to install GRUB on VM disk from the host. But it also means that GRUB will mistakenly allow install on real system as well. For now let's fix regression; future behavior needs to be discussed. Closes: 45163
This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
