SHA256 check for snapshots fails

Hello,

I have downloaded the 4-Nov-2009 snapshot from ftp.openbsd.org.
Running the `cksum -a sha256 -c SHA256` against .iso file I got the OK
result. After CD burning I run again the command agains files on the
CD - all the x*.tgz checksums are reported as FAILED. I thought it's
the damn burner fault ( quite strange because is a new one ) and I
used vnconfig with svnd0 to mount the .iso file and check - the result
is the same, again the x*.tgz checksums are reported as FAILED.

To get the big picture, things are like the .iso file is OK, but some
files inside it are FAILED. How that can be ? Is is ok to check the
SHA256 for snapshots anymore?

Thanks

"base" and "x" may be built at different times.
if that happens you might get the failure on the x* checksums.
just the way it is atm.

Hmm, I got the feeling that SHA256 will hold the checksums for the
existent files in that directory, plus the fact that files are used to
generate the .iso file. Am I wrong ?
I fail to see the link between build times and checksums ...
