So, enable dm-integrity on all LVs, including /, /var/lib/lxc, /scratch
and swap, now boots without any issue with grub2 as long as /boot is NOT
on the same VG where the dm-integrity over LVM RAID is enabled.
This is OK for me, I don't need /boot on dm-integrity.
update-grub gives out warning for every of the rimage subvolumes, but
can still then reboot.
I would guess the bug is thus in grub2, not yet supporting boot on a
/boot not necessarily dm-integrityfied itself, but on a VG where any
of the LV is.
Are readers seconding conclusion? If yes, I could report a bug on grub2.
Have a nice day.
