Dreamhost like hosting services?
 

Are there any other hosting companies that have one-click installs and upgrades for popular open source products as part of their hosting packages? Basically, I'm looking for something like Dreamhost but more of a VPS like alternative.

I think now almost every company has such updates.I know whm have that feature.

Any host with fantastico installed in their cpanel is better than dreamhost in that regard.
