very true

Smart looks nice and is moving along OK, and having a GUI is good.
Smart can use repomd (Repo MetaData) used by yum and the metadata used
by apt.  It also has a couple features that I like ... one of them is
signing a priority to a repo (ie, you can make packages in the base repo
have a higher score than a add-on repo.  This would only update absolute
requirements from the add-on repo.)

yum is also making progress with a sqlite backend.  This speeds up yum.
A new createrepo (creates the repomd data for yum) also now caches the
md5sums for packages, so it runs faster too.

I personally use yum ... though I have one test machine that is using
smart.  Even when I use smart, I use the CLI and not the GUI.

CentOS-4.2 will have an upgrade to yum 2.4.x and createrepo-0.4.3, which
requires a couple packages to be added to the distribution.  The new
pacakges will be:

createrepo-0.4.3-1.noarch.rpm (upgrade from 0.4.2)
yum-2.4.0-1.centos4.noarch.rpm (upgrade from 2.2.1)

One very good thing for CentOS is that Seth Vidal is one of the CentOS
Developers, so we will have extended yum support for the duration :)
