Dreamhost one click installs.

I don’t know if they’ve already had it but I noticed that Dreamhost now has an option in their one click installation routines that has a setting to email you whenever a new version comes out – this is great to ensure that you are aware of any new security patches. As they are one click installations it is very easy to upgrade the software but you do have to bear in mind that they may not have a new version as soon as it is released (although apparently their WordPress 2.5 came out hours after the official release).
