You can configure and setup workflows where a distributed Version Control
System (VCS) is centralized, but you can't configure a centralized VCS to
be distributed.  And besides the development workflow, git has other
desirable features (http://git-scm.com/about/) so people are switching to
git.

than a centralized one.  It should be stated that you can setup multiple
repositories per server in a centralized system, but you can also setup
multiple projects per repository when those projects are in any way
related.  Regardless of the workflow, I've found that merging with git is
1000x better than with svn (and that's with svn having what they call merge
tracking).  ClearCase is one of the few VCSes that I'm not familiar with
but I can say git is simply more powerful than svn.  Because of that there
is more to learn if you want to use those powers.  However, the basic
workflow can be mastered pretty easily.  Gitosis (
http://scie.nti.st/2007/11/14/hosting-git-repositories-the-easy-and-secure-way/)
is a simple yet very effective method for setting up your own Git server to
manage repositories for people.  Git can keep track of your own stuff and
you don't need to setup a server at all.

Speaking of servers, etckeeper (
http://www.serverwatch.com/server-tutorials/keep-configs-under-control-with-etckeeper.html)
is a simple yet effective method for tracking system configuration with
git/bazaar/mercurial.
