Description of problem:
Running 'yum -d 0 -e 0 check-update' in a crontab typically produces some output
even if no updates are available: the 'sqlite cache needs updating' message.
The '-d 0 -e 0' flags should function to supress this unnecessary gabbiness.

Version-Release number of selected component (if applicable):
yum-3.0.1-2.fc6

How reproducible:
Run 'yum -d 0 -e 0 check-update' in a crontab.

Steps to Reproduce:
1. Run 'yum -d 0 -e 0 check-update' in a crontab.
2. 
3.
  
Actual results:
Tedious and uninteresting output every time it runs

Expected results:
If there are no available updates, the above command should produce no output.

Additional info:
I know I can filter this out by piping it into a 'grep -v' in crontab. I
shouldn't have to, though.
