[Yum] new daily

[seth vidal]

Hi folks,
 New, potentially broken daily :)

http://www.dulug.duke.edu/yum/download/

Changes:

1. lock files enabled in yum - if you try to run yum as root in two
terminals at the same time it will yell at you and exit - you can run it
as a user as many times as you want b/c user's can't do anything

2. Header checking does _something_ now - if a header is downloaded it
gets checked, if it fails the check 3 times we exit, but it will
download it up to 3 times to check it.


that's it.
