[edit] RPM and Yum Enhancements

[edit] Summary

We feel the need - the need for speed.

• Speed up resolving below 2 minutes (better below one minute) in worst case (on a reasonably new computer)
• Reduce memory consumption significantly below 100MB for most cases - may be even for all cases

thl: Maybe also get rid of file deps outside of /etc, /bin, /sbin, /usr/bin, or /usr/sbin in our packages as much as possible, too, as they sometimes slow down yum's depsolving a lot? The Packaging Committee has something in the queue , but there is not much interest to drive it forward afaics.
