kernel (6.2 amd-64 mp) relinking failed on cloned disk

[Z Ero]

Hello

I cloned a disk that had OpenBSD installed via

dd if=/dev/r{source_dev} of=/dev/r{target_dev} bs=16m

Now when I boot from the cloned disk I get the following error
login: reorder_kernel: kernel relinking failed; see
/usr/share/compile/GENERIC.MP
/relink.log


When I cat "relink.log" I get
(SHA256) /bsd: FAILED

Does this mean that a machine specific hash / checksum required to
validate / execute the kernel relink is not working or what?

Otherwise the machine works fine.

Is the error a real cause for concern? Cloning a working setup with dd
as I did saves me a bunch of time vs. installing and configuring a new
system.

Also, how to correct the error, if possible?

Thanks

It compares /bsd with checksum in /var/db/kernel.SHA256
if it does not match kernel relinking is disabled because it
assumes you are a kernel developer and know what you are doing.

$ doas sha256 -h /var/db/kernel.SHA256 /bsd
