Subject: [PATCH] This change set makes several modifications:

1. it conditionally include certain "Requires" statements for specific
   distributions and their corresponding release.

2. it double checks that /sbin/new-kernel-pkg isn't linked to /sbin/true,
   as often is the case in vservers dueo the /etc/rpm/macros setup.

3. adds in 256 /dev/loop entries

4. turns off the "requirestty" option in /etc/sudoers
