>Description:
Certain i386 compat libraries show checksum mismatches when you run mtree:

Notice that only the checksums are wrong; the file sizes are the same.
No idea how this could happen, but, this is not a new issue (I think
I've noticed this last year too...)

NetBSD 9.2_STABLE reports this:

The files in /etc/mtree/ are the ones correctly merged by etcupdate(8).

 Updating to 9.99.98 produces a mismatch in a _different_ Kerberos compat
 library now:

 Well, the kernel version change in the ident section explains why all the
 SHA256 hashes are completely different now:

 ---
 Displaying notes found in: .note.netbsd.ident
    Owner                Data size        Description
    NetBSD                0x00000004      IDENT 999009800 (9.99.98)
 ---

 But, why is a _different_ Kerberos library showing a mismatch?
