This Engine Yard Gentoo 12.11 update includes a rebase off Hardened Gentoo, which provides a more secure stack for your application environments.
This new Engine Yard Gentoo 12.11 distribution is based off recent Gentoo, including Hardened Gentoo toolchain enhancements that provide mitigation against various exploit vectors and improve the security of all software within the distribution.
As a benefit, moving to this distribution means that weekly stack upgrades require less Chef recipes. This means faster booting and upgrade processes. As always, we encourage you to keep stack components as close as possible to the most recent releases.
Important: The primary consideration when you create and test an Engine Yard Gentoo 12.11 environment is to verify the version numbers for all stack components. The Engine Yard Gentoo 12.11 environment supports:
MySQL version 5.5.x if your app uses MySQL.
PostgreSQL version 9.2.x if your app uses PostgreSQL.
Select the Engine Yard Gentoo 12.11 Stack: stable-v4 and click Create Environment.
This displays the configuration choices for your Engine Yard Gentoo 12.11 environment.
On the Configuration page, select the environment setup you need.
If you choose the Single Instance, Staging Configuration, or Production Configuration, verify that it has pre-configured 64-bit instances under the Instance Details section. (If it doesn't, then you must choose Custom Configuration instead.)
If you choose Custom Configuration, be sure and select only 64-bit instance sizes.
Click Boot this Configuration.
Your Engine Yard Gentoo 12.11 environment starts up.
