Yep, that was it, thanks. It seems permissions were not copied through 
the backup process. For instance, now the /tmp dir wasn't writeable by 
common users either. I'm kind of worried that there's more stuff messed 
up. I used some back up instructions that were mentioned on this list a 
couple of weeks ago, with "cp -dpRv". Shouldn't this command correctely 
copy all the file permissions?

Thanks again,
