'sh freebsd-update.sh -f freebsd-update.conf rollback' was the command, 
but that is correct.

I did not think I was the first to do this rollback -- good that I 
tested it.

I guess I can download a 6.3-BETA1 cd and copy the files over from 
there. If you have a better way, please, let me know.

Not to be able to go back to 6.2-RELEASE is ok. If updating to 6.3-BETA2 
(and eventually perhaps 7.0) is not possible because of the mixed 
system, it will limit my testing and I will have to reinstall at some 
point, which would not be a disaster, either. (Sometimes I do testing 
that feels rather save on my main working machine -- I am glad I was not 
so insane this time.)

Is there any cleanup to do besides replacing the libs (such as removing 
temporary freebsd-update directories)?

Since your blog seems not to tell and there is no other documentation: 
Is freebsd-update -r supposed to work if not all files are from 
GENERIC/SMP? Does it skip files or overwrite them with GENERIC versions? 
(For security updates, the former might be desirable, but for updates 
between releases, only the latter would make sense to me.)
