I did, and it looks it does not seem to document anything pertaining to my issue: 1) I don't use integritysetup (from LUKS), but LVM RAID PVs -- I don't use LUKS encryption anyway on that system 2) the issue is not the kernel not supporting it, because when the system is up, it works (I have done tests to destroy part of the underlying devices, they get detected and fixed correctly) 3) the issue is not with the initrd -- I added the dm-integrity module and rebuilt the initrd (and actually the bug happens before grub2 loads the kernel & init) -- or at least "not yet"! maybe this will fail later :) 4) actually the issue is just grub2, be it when the system is up (it complains about the special subvolumes) or at boot time Having /boot on a LVM non enabled dm-integrity logical volume does not work either, as soon as there is ANY LVM dm-integrity enabled logical volume anywhere (even not linked to booting), grub2 complains (at boot time or at update-grub) about the rimage LV.
