So, LVM and md RAID do not checksum data blocks -- they need a disk to 
report a failed read before they realize something is wrong?

Thanks for the link.  I recall reading about dm-integrity sometime in 
the past, but my rotten old brain must have screwed it up.  At least I 
wasn't hallucinating when I guessed that LUKS had checksums.  8-O


My Debian 9 and cryptsetup are now looking even older and more inferior.


Does the Debian 10 installer make use of, or allow the use of, 
dm-integrity and/or cryptsetup with the --integrity option?  If not, 
does the necessary software exist in the d-i kernel, BusyBox, whatever, 
so I can do it by hand with the rescue console/ alternate virtual console?
