I am one of the developers for TurnKey Linux, an open source project
which recently released a new version of our Ruby on Rails appliance:
In a nutshell, this is an extremely easy way to get Ruby on Rails up
running on your server or VM (VMware, VirtualBox, Xen, KVM) of choice
just a couple of minutes.
Ruby on Rails can be a dream to program in, but for some users,
especially those lacking in technical proficiency it can be a bit
difficult to set up. We’re trying to make that easier.
Security: SSL support, crypto key regeneration during installation,
set database password during installation.
Usability: confconsole support for systems with multiple NICs,
password-free login in demo mode, and added many generically useful
Bugfix in the daily auto-updates mechanism.
Rebuilt on top of TurnKey Core, the new common base for all software
appliances, which is assembled from Ubuntu 8.04.2 LTS packages.
BTW, this was part of a wider release including 12 other new appliance
