Hi all,TL;DR: Dragora 3.0 beta 2 ships with GRUB 2.06 that fails to recognize ext4 root partition, it should be upgraded to 2.12.
I tried to install Dragora on a qemu VM. I used the whole disk for the root partition, with MBR and bootable flag. Then I formatted the root partition as ext4 like I always do. Then grub-install failed.
grub-install: error: unknown filesystem I believe this is the exact bug reported here [1]. [1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=866603If I follow the workaround in [2] to disable an ext4 feature "metadata_csum_seed", yes, grub-install would succeed, but only grub could only be installed on MBR, not superblock:
# (after bind mount and chroot)# grub-install --taget=i386-pc --boot-directory=/boot --directory=/usr/lib/grub/i386-pc /dev/sda1
grub-install: warning: File system ext2 doesn't support embedding.grub-install: warning: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged..
grub-install: error: will not proceed with blocklists.After installing grub to MBR, unfortunately after reboot, there was a "kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(0,0)". If I re-enable "metadata_csum_seed", then grub couldn't boot (unknown filesystem).

This is so unfortunate I ended up with a broken install :( But there seems to be a patch [3] that can solve this. Or better: upgrade GRUB to 2.12 where the patch was merged.
